Here's how it is given:
Stone's variables:
vi = 0m/s
a = 9.8m/s*2
t = ?
d = .5at*2 = (4.9m/s*2)(t*2)
Ball's variables:
vi = +20m/s
a = -9.8m/s*2
t = ?
d = vit + .5at*2 = (+20m/s)t + (-4.9m/s*2)(t*2)
d1 + d2 = 50m
(4.9m/s*2)(t*2) + (+20m/s)t + (-4.9m/s*2)(t*2) = 50m...
Homework Statement
A stone is dropped from the top of a 50m high tower at the same moment as a ball is thrown straight upward from the bottom of the tower, with an initial velocity of 20m/s. when and where do the ball and stone pass each other?
