This question is about throwing a ball vertically upwards and catching the ball.

Compare the part of the graph of mechanical energy vs. time before the ball is in free-fall to the part while the ball is in free fall. Carefully explain, using the concept of work done on the system, why the ball’s mechanical energy changed as it did.

A 60 kg soccer player jumps vertically upwards and heads the 0.45 kg ball as it is descending vertically with a speed of 27 m/s. If the player was moving upward with a speed of 4.0 m/s just before impact, what will be the speed of the ball immediately after the collision if the ball rebounds vertically upwards and the collision is elastic? ______m/s If the ball is in contact with the player's head for 20 ms, what is the...

1. You throw a 50kg ball upwards at 25m/s. The ball strikes the beginning of the spring when it's 8 meters in the air, then it begins to compress the spring. How far did the spring compress? The spring constant is 300 Newton/meter. Also, if the spring was not there, how far would have it gone up (set the final velocity to zero)? 2. You see a teeter-todder again. It's horizontal (balanced). A 100kg person sits 4 meters to the...

a toy rocket is fired fired at rest vertically upwards and accelerates at a constant rate. At the instant the engine cuts out, the rocket has risen to 52 m and acquired a velocity of 80 m/s. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground with negligible air resistance. The speed of the rocket upon impact on the ground is closest to

We often think about two-dimensional motion in terms of a projectile, like someone throwing a ball up in the air. Consider, instead, the surface of an air-hockey table, where the puck travels horizontally from one end of the table to the other. Imagine you’re standing at one end of the table and answer the following questions in your initial post to the discussion. 1. Describe the shape of the puck’s path, starting from the end of the table where you’re...

A ball is thrown upwards from the roof of a house that is 20m tall. The initial velocity V0 is 10m/s, and the acceleration due to gravity g is 10m/s2. Find: a) The maximum height that the ball reaches in the air. b) The total time of flight. c) The hitting velocity (the velocity right before the ball hits the ground). d) Its velocity at t=2s.

A basketball player, about to "dunk" the ball, jumps 76 cm vertically. bout to "dunk" the ball, jumps 76 cm vertically. (a) How much (total) time does the player spend in the top 25 cm of this jump? (b) How much (total) time does the player spend in the bottom 25 cm of this jump? ms (c) Does this help explain why such players seem to hang in the air at the tops of their jumps?
