Question

A cannonball is fired horizontally from the top of a 63 m high cliff. It lands on an invading ship that is 430 m away from the base of the cliff.
At what speed was the cannonball launched?


A) 120 m/s

B) 33 m/s

C) 17.5 m/s
How long does it take to fall 63m?
4.9t^2 = 63
The horizontal speed remains constant, at 430/t m^s
Thank you for helping, but does that mean the answer isn't any of the multiple choices given?
