Chapter 2: Q. 44 (page 61)

Draw position, velocity, and acceleration graphs for the ball shown in FIGURE P2.44. See Problem 43 for more information.

Short Answer

Expert verified

Initially, the ball is stationary at a maximum position resulting in zero velocity. The position-time graph shows that with increasing time the ball is coming down from its maximum position to minimum position and then follows the parabolic path. The velocity of the ball increases in the negative direction becomes maximum and then decreases with increasing time. From the acceleration-time graph, it can be observed that the acceleration has a constant negative value initially and it goes from negative to a positive constant value as the ball reaches the minimum position in the given diagram.

Step by step solution

01

Given information

The given figure is

02

Position-versus-time graph

Let s be the distance along the track measured from the left and t be the time.

The graph of position-versus-time is shown below

03

Velocity-versus-time graph

Let vsbe the velocity of the ball. The graph of velocity-versus-time for the given situation is shown below

04

Acceleration-versus-time graph

Let asbe the acceleration of the ball. As the angle of inclination is the same, the magnitude of the acceleration is the same on all tracks. The graph of acceleration-versus-time for the given situation is shown below

The position of a particle is given by the function x = 12t 3 - 9t 2 + 122 m, where t is in s. a. At what time or times is vx = 0 m/s? b. What are the particle鈥檚 position and its acceleration at this time(s)?

You are at a train station, standing next to the train at the front of the first car. The train starts moving with constant acceleration, and 5.0 s later the back of the first car passes you. How long does it take after the train starts moving until the back of the seventh car passes you? All cars are the same length.

A 1000 kg weather rocket is launched straight up. The rocket

motor provides a constant acceleration for 16 s, then the motor stops. The rocket altitude 20 s after launch is 5100 m. You can ignore any effects of air resistance. What was the rocket鈥檚 acceleration during the first 16 s?

Two cars are driving at the same constant speed on a

straight road, with car 1 in front of car 2. Car 1 suddenly starts

to brake with constant acceleration and stops in 10 m. At the

instant car 1 comes to a stop, car 2 begins to brake with the

same acceleration. It comes to a halt just as it reaches the back of car 1. What was the separation between the cars before they starting braking?
