Document Summary

You launch a ball with some initial velocity up a ramp. The ball slows down, barely making it to the top of the ramp, then falls off, hits the ground below and rebounds. Draw a complete motion diagram of the ball from the time it is released until it hits the ground. Be sure to show the acceleration at the lowest point! (4 pts) When the ball is on its way down, catch it at point b which is lower than a. She then strolls slowly to r, stays there a moment, and then runs quickly back to p. Which of the position vs. time graphs below correctly represents this motion? (3 pts)

you reach out of your dorm window and throw a ball upward with andinitial velocity Vo
and it hits the ground after a time Tf. we also know the magnitudethe acceleration due to gravity is g.

lets agree that t = 0 is the instant the ball is released, up is +and down is -.

determine expressions for the follow physical quantities in termsof only the known information Vo Tf and g

1) time for the ball to get to the top of the trajectory.

2) Distance the ball travels above the point where it isreleased

3) Time it takes for the ball to get to the top of the trajectoryand back to its original height

2) [4 pts]You throw a ball vertically upwards and catch it some time later at the same height you threw it from. Draw a position-vs-time graph and a velocity-vs-time graph for that motion, from the instant you release it until you catch it.

A hard rubber ball, not affected by air resistance in its motion, is tossed upward from shoulder height, falls to the sidewalk rebounds to a smaller height, and is caught on its way down again. This motion is represented in Figure OQ2.17, where the successive positions of the ball A through E are not equally spaced in time. At point D the center of the ball is at its lowest point in the motion. The motion of the ball is along a straight, vertical line, but the diagram shows successive positions offset to the right to avoid overlapping. Choose the positive y-direction to be upward. (a) Rank the situations A through E according to the speed of the ball at each point, with the largest speed first. (b) Rank the same situations according to the acceleration of the ball at each point. (In both rankings, remember that zero is greater than a negative value. If two values are equal, show that they are equal in your ranking.)
