Question

A football is kicked at an angle of 37° with a velocity of 20m/s the ball is at ground level . Find the maximum height

Answer 1

Answer:

A football is kicked at an angle of 37 degrees with a velocity of 20 m/s.

You didn't specify the Earth's gravitational acceleration.

I'll use 10 m/sec^2

Maximum height

Vertical component Vy = 20*sin(37) =12.036 m/sec

Flight time = 12.036*2/10 = 2.407 seconds

h(t) = -5t^2 + 12.036t

Max is the vertex

t = -b/2a = 12.036/10 = 1.2036 seconds

h(1.2036) = 7.243 meters Max height
