first ball:
hf=vi1t-4.9t^2
second ball
hf=vi2(t-5)-4.9 (t-5)^2
you know vi1, hf. You do not know t, vi2.
in the first equation, solve for t.
then, in the second equation, solve for vi2
using a powerful air gun, a steel ball is shot vertically upward with a velocity of 80 m/s, followed by another shot after 5 seconds. find the initial velocity of the second ball to meet the first ball 150 m from the ground.
