Two Dimensional Projectile Question:

Determine the height reached by a baseball if it is released with a velocity of 17.0 m/s [at an angle of 20 degrees]

1 answer

It rises for a time T such that
Vo sin 20 = g T
T = Vo sin 20/g = 0.5933 s

The height reached is
(Vo sin20)*T/2 = (Vo sin20)^2/(2 g)
