It is the case of projectile motion in which the projectile fires from the ground and again it hit the ground.
The angle of projection is 32 degree and the velocity of projection is 20 m/s
he velocity at the maximum height is equal to the horizontal component of velocity which always remains constant as there is no acceleration along x axis.
Velocity at the highest point = u Cos 32 = 20 x Cos 32 = 16.96 m/s
