A stone is thrown vertically upward at a speed of 48.00 m/s at
time t=0. A second stone is thrown upward with the same speed 4.050
seconds later. At what time are the two stones at the same
height?
Set up an equation of motion for each stone. Write the time for
the second stone in terms of the time for the first stone. Solve
the two equations for the unknown time.

An object is thrown upward with an initial velocity of 32.1 m/s.
When the object reaches it maximum height, it is true of the
acceleration, a, and the velocity, v, that:
both its acceleration and velocity are zero
both its acceleration and velocity change sign
velocity is equal to zero, but acceleration is not
acceleration is equal to zero, but velocity is not
None of the above.

A blue ball is thrown upward with an initial speed of 24.3 m/s,
from a height of 0.9 meters above the ground. 3 seconds after the
blue ball is thrown, a red ball is thrown down with an initial
speed of 8.2 m/s from a height of 33.3 meters above the ground. The
force of gravity due to the earth results in the balls each having
a constant downward acceleration of 9.81 m/s2.
