Question

An object is launched from the ground into the air at an angle of 38.0 o (above the horizon) towards a vertical brick wall that is 15.0 m horizontally from the launch point. If the ball takes 1.30 seconds to collide with the wall, with what speed was the ball launched?

In projectile motion, we can use the formula,
d = vo,x * t
or
d = vo cos(a) * t
where
d = distance traveled horizontally
vo = initial velocity
vo,x = initial horizontal velocity
a = angle
t = time

Substituting,
15 = vo * cos(38) * 1.30
vo = ?
