Thank you so much.

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? Homework Equations I actually have the...
