Question

The local football player is practicing football on top of a 25 m high hill. He kicks the soccer ball, which lands 40 m from the base of the hill. Determine the initial horizontal velocity of the ball. Round off to 1 decimal place.

Answer 1

Assuming a cliff, instead of a hill (the base of a hill could be some distance away), how long does it take to fall 25m?
4.9t^2 = 25
since the horizontal speed is constant,
v = 40/t

Answer 2

1.6

Answer 3

The initial horizontal velocity of the ball is approximately 1.6 m/s.
