Problem 1

A rock is dropped off of a m tall building.  What is the velocity of the rock right before it hits the ground?  How much time does it take to hit the ground? (Ignore air resistance)

Velocity = m/s

Time =   sec

Problem 2

A marble is launched straight upwards from a slingshot with a velocity of m/s.  Calculate the maximum height of the marble. (Ignore air resistance)

Max. Height =  m

Problem 3

A bullet is fired straight up with a velocity of m/s.  What is its height after sec? (Ignore air resistance)

Height  =  m
