You kick a ball on the ground, with an aim to hit a wall at height h above the ground. The initial velocity of the ball is 20 m/s and it makes an angle of 30° with respect to the ground. The wall is 15 m away from you. (a) Find the height h at which the ball will hit the wal (b) Find the angle 0, at which the ball will hit the wal (c) When it hits the wall, has the ball already passed the highest point on its trajectory? Show your working.
