(A to B; B to C and C to D). Label all the vectors clearly.
(Use a scale of 1cm = 20m) (3)

2.2.2 On the vector scale diagram draw and indicate the resultant

displacement for his motion. (1)
2.2.3 Calculate the total distance covered by the athlete. (1)

2.2.5 Calculate the average velocity of the athlete. (4)

2.3. An aeroplane flies, in a straight fine, due east to its destination which is
2 200 km away. The pilot wishes to maintain an average speed of 550 km.h”!
in order to arrive on time.

QUESTION 5

Vusi, of mass 45 kg, wants to reach an apple 2,5 m above the ground in an apple
tree. He connects a swing to a high branch in an adjacent tree. The bottom of the
swing is 1,15 m above the ground. He asks his friend, David, to push him in an effort
to reach the apple. Ignore the effects of any frictional forces.

2.5m ft
5.1. Define the term gravitational potential energy. (2)
5.2 Calculate the gravitational potential energy of Vusi on the swing before
David pushes him. (3)
5.3 State the law of conservation of mechanical energy in words. (2)

5.4 Use energy principles to calculate the minimum speed with which David
needs to push Vusi so that he can reach the apple in the tree. (4)

5.5 Why is it NOT possible to use equations of motion to calculate the speed
mentioned in 5.4? (1)

5.6 Vusi now decides to adjust the seat of the swing so that it is brought closer
to the ground. Will the speed with which David needs to push Vusi in order to
reach the apple be GREATER THAN, LESS THAN or THE SAME AS that
calculated in 5.4? Explain your answer without using any calculation. (5)
