A ball is thrown at 22 m/s at 45 degrees to the horizontal. A 5 foot tall fence is located 100 meters away. Does

the ball make it over the fence?

1 answer

You can use the range equation to figure this out, first, if the ball even makes it to 100m.

horizontal distance=R=Vi^2*Sin2(Theta)/g

Where

Vi=22m/s
Theta=45
and
g=9.8m/s^2

Solve for R:

R=(22m/s)^2*Sin2(45)/(9.8m/s^2)

R=(22m/s)^2*Sin2(45)/(9.8m/s^2)

R=49.39m

The ball doesn't make it that far.
