Motion (Past Paper Style)

An object is moving with uniform deceleration. Which statement describes its motion?

(Past paper 2019)

• Its rate of change of speed is decreasing.

• Its speed is constant.

• Its speed is decreasing.

• Its speed is increasing.

The graph shows how the speed of a car varies during part of its journey. What is the value of the car’s acceleration between 6 s and 10 s?

(Past paper 2019)

• 0.5 m/s²

• 1 m/s²

• 1.25 m/s²

• 1.5 m/s²

On another part of the journey, the average speed of the bus is 7.5 m/s. Calculate the distance the bus travels in 150 s. Distance = .... m

Fig. 1.1 shows the distance-time graph for the journey of a cyclist. Describe the motion of the cyclist in the time between:

1. time = 0 and time = 15 s ​ ​ (a)  

2. time = 15 s and time = 30 s ​ ​ (b)  

3. time = 30s and time = 40s. ​ (c)  

4. the average speed for the 40s journey: ​ (d)   m/s

5. the maximum speed ​ (e)   m/s

A rocket is launched vertically upwards from the ground. The rocket travels with uniform acceleration from rest. After 8.0s, the speed of the rocket is 120m/s. Calculate the acceleration of the rocket!

Acceleration = .... m/s²
