A car is moving with a velocity 20 m s ^-1 . The brakes are applied to retard it at a rate of 2 m s ^-2. What will be the velocity after 5 s of applying the brakes ?

A bicycle initially moving with a velocity 5.0 m s ^-1 accelerates for 5 s at a rate of 2 m s^-2 . What will be its final velocity?

The slope of displacement-time graph gives:

1. Velocity
2. Acceleration
3. Speed
4. Displacement

From the given displacement-time graph, answer the following questions:

(i) The kind of motion depicted in this graph is :

1. uniform
2. non-uniform
3. retardation
4. all of the above

(ii) The velocity between point A and C is:

1. 20 ms^-1
2. 5 ms^-1
3. 10 ms^-1
4. 15 ms^-1

(iii) The displacement at t = 3s is:

1. 15 m/s²
2. 12.5 m/s²
3. 40 m
4. 30 m
