You are throwing for a three pointer. The ball leaves your hand with a velocity of 9.4 m/s at an angle of 60 degrees with the horizon. You score from a horizontal distance of 7 m. The height of the basket is 3.5 m. (Ignore air-resistance)

a) Draw a free body diagram of the ball.

b) Find the position and velocity of the ball as a function of time

c) At what height was the ball released?

d) What is the velocity in the vertical direction as the ball hits the goal?

1. Assume that in the process of throwing a baseball pitch, the baseball leaves the hand of the pitcher 6 vertical feet above and 60 horizontal feet from home plate. Also assume that your coordinate axes are such that the origin is at ground level directly below the point of release. (a) On the first pitch, the pitcher throws a 140 ft/sec (≈ 95 mph) fastball directly at the center of the strike zone. In the absence of all forces...

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 ball is rolled off a table and at the very instant the rolling ball leaves the table a second ball from rest is dropped from the same height above the floor as the table. From the above why is the horizontal and vertical parts of the ball's motion independent of one another? Does the vertical part of the motion change when the horizontal part does? How does the vertical part of the motion of the ball rolling off the...

In this problem, consider Tom and Jerry in space and throwing a ball back and forth. Initially, they are at rest with respect to each other and are separated by a distance L0. For simplicity assume that they have the same mass, and that they both always throw the ball with the same speed V. a) If they are in ”open space” (no walls or ropes) what happens? i) To answer this, continue drawing a sequence of sketches below showing...
