A ball is thrown horizontally from the top of a building 22.5 meters high?

Question

The ball strikes the ground at the point 125 m from the base of the building. The acceleration of gravity is 9.8

I know the time the balls in motion is 2.14

I just need to knowthe initial velocity of the ball.

Can someonen help?

Answer 1

Check the fall time
y(t)=22.5-.5*9.8*t^2
when y(t)=0, impact

Yes, the flight time is 2.14 seconds

x(t)=v0*t
x(2.14)=125=v0*2.14

v0=58.3 m/s
