Question 5.5 · May/June 2023 · Paper 1 · National (DBE) · 4 marks

An electric motor pulls a

20

kg crate from rest at point A up an inclined plane by means of a light inextensible rope. The inclined plane makes an angle of

18°

with the horizontal. B, C and D are points on the inclined plane and the distance between points A and C is

15, 6

m, as shown in the diagram below.

The motor exerts a constant force of

96, 8

N parallel to the inclined plane on the rope.

A constant frictional force of

13, 5

N acts on the crate as it moves on the inclined plane. Diagram for this question

5.5 Draw a velocity-time graph for the entire motion of the crate starting from point A until it passes point B again on its motion down the inclined plane.(4)

Work it out on paper first. Then mark yourself with the official memo, one tick at a time.

4. Question 5.3.2 · May/June 2025 · Paper 1 · National (DBE) · 3 marks
Water is drawn from a water source $12, 5$ m below the ground by an electric pump. The water is lifted vertically upwards at a constant speed, as shown in the simplified diagram below.

The pump lifts the water upwards at a rate of $2, 5$ kg·s $^{- 1}$ . Ignore ALL frictional and capillarity effects.
5.3 The pump lifts $200$ kg of water from the source to the ground at a constant speed. Calculate the:

6. Question 1.2 · November 2018 · Paper 1 · National (DBE) · 2 marks
1.2 A car is travelling at a speed of $30$ m·s $^{- 1}$ on a straight road. What would be the speed of the car in km·h $^{- 1}$ ?(2)
1. A $8, 33$ km·h $^{- 1}$
2. B $30$ km·h $^{- 1}$
3. C $108$ km·h $^{- 1}$
4. D $130$ km·h $^{- 1}$

  Correct optionTo change m·s $^{- 1}$ to km·h $^{- 1}$ , multiply by $3, 6$ (there are $3600$ s in an hour and $1000$ m in a km):
  $30 \times 3, 6 = 108$ km·h $^{- 1}$ .
  Option A divides by $3, 6$ instead of multiplying.
