A two balls are released simultaneously from the top of a, Ask an Expert

Academics

A. Two balls are released simultaneously from the top of a tall building. Ball A simply dropped with no initial velocity, and Ball B is thrown downward with and initial velocity of 12 m/s. What are the velocities of the two balls 1.5 seconds after they are released?

B. How far has each ball dropped in 1.5 sec?

C. Does the difference in velocities of the two balls change at anytime after they are released? Explain.
