Problem
A 0.45kg soccer ball is kicked from ground level with a speed of 18m/s at an angle of 37∘ above the horizontal. Neglect air resistance.
(a) Determine the horizontal and vertical components of the ball’s linear momentum immediately after it is kicked.
(b) Find the magnitude of the ball’s linear momentum at the highest point of its trajectory.
(c) Calculate the ratio of the magnitude obtained in part (b) to the magnitude of the initial momentum. Explain physically why the ratio has that value.
