Two students are on a balcony a distance h above the street. One student throws a ball vertically downward at a speed vi ; at the same time, the other student throws a ball vertically upward at the same speed. Answer the following symbolically in terms of vi , g, h, and t. (a) What is the time interval between when the first ball strikes the ground and the second ball strikes the ground? (b) Find the velocity of each ball as it strikes the ground. (c) How far apart are the balls at a time t after they are thrown and before they strike the ground?

Two balls are separated by an some vertical distance h (in meters) from each other. The first ball is thrown down with an initial velocity voi = -3.0 m/s and the other one is thrown up from the ground with an initial velocity vo2 = 3.0 m/s at the same time the other is thrown. How far, in meters, must they be separated so they hit the ground at the same time?

A physic student sets out to experiment on the effect of drag forces on a ball of mass m by giving the ball an initial velocity nu_0 upwards and then downwards as describe below. In both cases, the ball experiences a force of air resistance whose magnitude is given by F = -k nu Where k is a positive constant. The positive direction for all vector quantities is taken to be upwards. Express all algebraic answers in terms of m....
