Assuming the ball's initial velocity was 57° above the horizontal and ignoring air resistance, what did the initial speed of the
ball need to be to produce such a home run if the ball was hit at a point 0.9 m (3.0 ft) above ground level?
Assume that the ground was perfectly flat. Express your answer using two significant figures. v₀ = ______ m/s
How far would the ball be above a fence 3.0 m (10 ft) high if the fence was 116 m (380 ft) from home plate? Express your answer using two significant figures. h = _______ m

Explanation:
Given that,
Lightning flashes one mile (1609 m) away from you.
We need to find the time it take the light to travel that distance. Let the time be t. We know that,
speed = distance/time
So, the required time is
