A projectile is launched from ground level at 55 m/s at a 35 degree angle. Air resistance is negligible.

a) What is the maximum height reached by the projectile?

b) What is the velocity (magnitude and direction) of the projectile at t=2.0 s?

c) A target with an adjustable height is placed 215 m away from where the projectile is launched. How high should the target be adjusted so that the projectile hits the top of the target on its way down?
