A ball is thrown horizontally from the roof of a building 54 m tall and lands 50 m from the base. What was the ball's initial speed?
I have been set this question and I'm a little stuck...here is the information I have extracted from the question:
sv = -54
sh = 50
v = ?
a = -9.81
I don't know what else I can do, or what formulas/principles I should be using. I can't modulate with Pythagoras as surely the ball wouldn't travel downwards in a straight line to it's resting point...any help?
Much appreciated,
Rory
