1. A racing car accelerates uniformly through three gear changes with the following average speeds:

$20 \, \text{m} \, \text{s}^{-1} $ for 2.0 s

$40 \, \text{m} \, \text{s}^{-1} $ for 2.0 s

$60 \, \text{m} \, \text{s}^{-1} $ for 6.0 s

What is its average speed?

2. A ball is thrown downwards at a velocity of 8 m/s and bounces upwards. Which of the following is its velocity-time graph?

[Assume no air resistance or energy lost and take downwards motion as positive direction]

Ball 1 Ball 2 Ball 3 

4) None of the above

 
3. A car, with an initial speed of $3 \, \text{m s}^{-1} $, accelerates at a rate of $2 \, \text{m s}^{-2} $ for 10 seconds. What is the speed of the car after the 10 seconds.
4. A vehicle travelling at 40 m/s accelerates uniformly at $5 \,\text{m}/\text{s}^{2}$ for 20 seconds. What is its final speed?
5. What information would you expect to find from a given velocity-time graph?
6. A ball, located an at initial height h, is thrown downwards. The ball has an initial velocity of $10 \, \text{m s}^{-1} $ downwards and takes three seconds to reach the ground. What is the initial height, h? $ \left( g = 10 \, \text{m s}^{-2} \right)$
7. A car travelling at 70 km/hr slows down to 50 km/hr in 30 minutes. What is its acceleration?
8. What must change when a body is accelerating?
9. A car accelerates from $3 \, \text{m s}^{-1} $ to $9 \, \text{m s}^{-1} $ in 2 seconds. What is its average speed?
10. A train travelling at an average speed of 60 km/hr comes to a complete stop in 20 minutes' time. What is its deceleration?
