. At moment of time t=0 a projectile
is fired directly upward with an initial velocity 100 ft/sec, and
initial height 250 ft. Find: a) velocity and acceleration after
t seconds, (b) velocity after 5 sec., (c) time of travel
to the highest point, (d) time of travel from the highest point to
the ground.
The equation of motion is h"=-32, where h(t) is the height
of projectile at moment t.
