1. 30.0 ms-1
2. 32.5 ms-1
3. 21.3 ms-1
4. 20.0 ms-1

2.  A car took 3 hours to travel from Kuala Lumpur to Ipoh. It moved with a speed of 80kmh-1 for the first 2 hours and 100kmh-1 for the last 1 hour. What is the average speed of the car for the journey in kmh-1?

1. 90 kmh-1
2. 86.7 kmh-1
3. 60 kmh-1

3.  Which of the following quantity must be changing if an object is moving at constant acceleration?

2. The direction of the body
3. The speed of the body
4. The acceleration of the body

4.  A bus increases its velocity from 20 kmh-1 to 92 kmh-1 in 5s. What is the acceleration of the bus?

1. 4.0 ms-2
