CAIE A-Level Physics AS 5.1.1 The Concept of Work and Recall and Use Work Done Force Displacement in Questions question 1

[Maximum number: 2]

The ball in (b) leaves the toy at point A and moves vertically upwards through the air. Point B is the position of the ball when it is at maximum height h above point A , as illustrated in Fig. 3.2.

The gravitational potential energy of the ball increases by 0.60 J as it moves from A to B .

Determine the average force due to air resistance acting on the ball for its movement from A to B.
average force = N
