This is for a college physics 100 level class.

A regulation ping-pong ball has a mass of 2.7 grams and a diameter of 40 mm. If this ping-pong ball is dropped from a height of 4.0 meters, how long will it take to reach the ground, and how fast will it be traveling right before it hits the ground? (Air resistance is not negligible.)

Please include an explanation of the process.

A student is trying to toss a ping-pong ball into a paper cup. If the ball is thrown at a height of 1.524 meters with an initial velocity of 6 m/s and at an angle of 60°, how far away does the cup need to be placed on the ground in order for the ping-pong ball to make it into the cup. Neglect air resistance. (3.90 m)

A small cannonball is shot straight up from the ground with a launch speed of 26.3 m/s. 2.00 seconds after the cannonball is launched, a ping pong ball is dropped from a height of 36.5 m. Both objects only move in the y-direction. 2a. Where (with respect to the ground) do the cannonball and the ping pong ball pass one another? 2b. How fast and in what direction are each of the balls traveling when they pass one another? 2c....

1. Physics and astronomy student club has a recently established tradition of pumpkin drop, from the top of Wick Science Building to the "moat" below street level. Although the "experimental data" have not been made public, there have been rumors of the drop took 2.07 seconds, i.e. falling from rest with negligible air drag. Based on the rumor, how tall is the building from the "moat" to the roof? Ignore air drag or any rotation of pumpkins. Hint: You may...
