D  400N (2)

1.4 Arocket of mass, M, has a weight, W, on the surface of the earth. The
rocket is blasted off to a height equal to the earth’s radius. At this point the
mass of the rocket has decreased to “2 M because some of the fuel has

been used up. The gravitational force of attraction between the rocket and
the earth at this height is...

QUESTION 2 (Start on a new page)
During a rescue mission, a stationary helicopter lifts a soldier of mass 75 kg,

vertically upwards at a constant acceleration of 0,4 m:s*, by means of a rope.
Ignore the effects of air friction when answering the following questions.

2.1. State Newton’s Second Law of Motion, in words. (2)

2.2 Drawa labelled free-body diagram showing all the forces
acting on the soldier while he is being lifted vertically upwards. (3)

2.3 Calculate the magnitude of the force which the rope exerts on the
soldier while the soldier is accelerating upwards at 0,4 m-s™. (4)

The helicopter now accelerates vertically downwards.
2.4 How will the tension in the rope be affected?

(Choose from INCREASES, DECREASES, NO EFFECT) (2)

QUESTION 4 (Start on a new page)

The diagram below represents a minibus of mass 3 200 kg travelling
at 12 m-s” on a straight horizontal road to the right. A car of mass 1 400 kg
is travelling towards the minibus on the same road.

The minibus collides with the car. Both vehicles come to an immediate stop after
the collision. The above system must be taken as a closed system.

4.1 What is meant by a CLOSED SYSTEM? (2)

4.2 How does the magnitude of the initial momentum of the minibus compare
to the magnitude of the initial momentum of the car?
(Choose from GREATER THAN, EQUAL TO OR LESS THAN) (1)

4.3. State, without performing a calculation, whether the collision between the
minibus is elastic or inelastic. (2)

4.4 The speed limit on this road is 20 m-s™.
Determine, by doing the necessary calculations, whether the car was
travelling within the speed limit. (5)
