2. In this question, two marks are available for the quality of written communication.

Fig. 2.1 shows the path of a ball after it is thrown from T. The ball reaches a maximum height at point P and then returns to the ground at G.

shows the path of a ball after it is thrown from T. The ball reaches a maximum height at point P and then returns to the ground at G.

(a) Assuming no air resistance, describe and explain how the vertical and horizontal components of the velocity of the ball change as it travels from T to G. [5]

(b) Assuming no air resistance, describe the changes in the kinetic and potential energies of the ball as it travels from T to G. [4]

(c) Describe how the motion of the ball is affected when air resistance is taken into consideration. [3]
