## Essential University Physics -Richard Wolfson Solutions Chapter 1 .pdf

Asking a study question in a snap - just take a pic. Section 2. The problem statement does not give us the times for the intermediate flights, nor the length of the layover in Kansas City, so we will have to assign these values ourselves.

Furthermore, because each segment of the trip involves a constant velocity, the instantaneous velocity is equivalent to the average velocity, so we can apply Equation 2. The average velocity for the overall trip is labeled v. ASSESS Although none of instantaneous velocities are equivalent to the average velocity, they arrive at the same point as if you traveled at the average velocity for the entire length of the trip.

## Welcome to Reddit,

Recall that instantaneous velocity is the tangent to the graph at any point, and that the average velocity is simply the total distance divided by the total time.

DEVELOP We know that the largest instantaneous velocity corresponds to the steepest section of the graph because this is where the largest displacement in the least amount of time occurs [see region a of figure below]. For the instantaneous velocity to be negative, the slope of the tangent to a point on the graph must descend in going from left to right, so that the final position will be less than the initial position [see region b of figure below] A region of zero instantaneous velocity is where the tangent to the graph is horizontal, indicating that there is no displacement in time [see regions c of figure below].

Finally, we can apply Equation 2. We must also understand that zero velocity occurs where the slope i. The derivative of a function of the form bt n can be obtained by using Equation 2. Note also that the units for part b come out to be s, as expected for a time.

We are asked to find the average acceleration.

The kinematics are one-dimensional, and we are asked to find the average acceleration over the braking period. We will also need to convert units from min to s to express the quantities in consistent units and from km to m to express the answer in convenient units.

The acceleration is positive, which means the velocity of the space shuttle increased during this period.

We need to find the average acceleration for both stages. Insert these values into Equation 2. It is in the same direction as the velocity so the velocity increases during this stage.

For stage ii , the acceleration is in the opposite direction i. Notice that this is similar to the previous problems, except that we are given the velocity and acceleration and are solving for the time, whereas before we were given the velocity and time and solved for acceleration.

The kinematics are one-dimensional. Given the supersonic nature of the vehicle, the value of a is completely reasonable.

The distance traveled during the given time is the difference between x and x0. Insert these quantities into Equation 2. Motion in a Straight Line Because we know the time to only a single significant figure 6 s , we should report our answer to a single significant, which is m.

Thus, by differentiating the displacement x t given in Equation 2. Notice that we have used Equation 2. Equation 2. We are asked to find the acceleration and the assent time for a rocket given its speed and the distance it travels.

Solve this equation for acceleration for part a. Once the acceleration is known, the time elapsed for the ascent can be calculated by using Equation 2. Therefore, from Equation 2. This enables the rocket to reach a speed of 2. Thus, given the initial and final velocity and the time interval, we can solve for acceleration.

This is the equation we shall use to solve for a. The value is in accordance with our driving experience. We are only asked to consider the rapid deceleration that occurs when they slam into the tungsten target. We are not asked what the deceleration is, but merely what distance the electrons penetrate the tungsten before stopping. We are asked to calculate the distance traveled by the rock before it hit the water.

Insert this data into Equation 2. The depth of the well is about the length of an American football field. We are asked to calculate the initial velocity required for an object to travel a given distance under the influence of constant acceleration directed opposite to the initial velocity.

These quantities are related to the initial velocity v0 by Equation 2. We are asked to find the maximum altitude reached by a model rocket that is launched upward with the given velocity. In addition, we need to find the speed and altitude at three different times, counting from the launch time.

For parts b , c , and d , use Equation 2. The second quantity should be rounded to 40 m because both non-zero terms in Equation 2. ASSESS As the rocket moves vertically upward, its velocity decreases due to gravitational acceleration, which is oriented downward.

## Essential University Physics

Upon reaching its maximum height, the velocity reduces to zero. It then falls back to Earth with a negative velocity.

Calculating the time it takes to reach its maximum height using Equation 2. We are asked to calculate how high a ball will rise and how long it remains airborne given its initial velocity.

ASSESS If the ball goes straight up as it leaves the bat and stays airborne for almost 5 s, what are the chances the catcher will catch the ball? These quantities are related by Equation 2.

These conditions are met by our result. We need to find the acceleration due to gravity on an unknown planet, and to identify the planet by comparing our result with the data in Appendix E.Username Password Forgot your username or password?

We need to find the acceleration due to gravity on an unknown planet, and to identify the planet by comparing our result with the data in Appendix E. DEVELOP We can break this problem into two segments: the time it takes the ball to travel from pitcher to catcher, and the time it takes the catcher to get the ball to second base. The duration of this CD phase can be calculated using Equation 2.
