Find the distance AB.

112.5

Sketch a distance-time graph for the journey of the car from A to B.

Find the acceleration of the particle when t = 4

0.25ms-2

show that XY … metres.

find the two possible values of c part 1

find the two possible values of c part 2

find the two possible values of c part 3

show that R = 500

find the value of T

860N

show that, after the towbar breaks, the deceleration of the trailer is 5/6ms-2

find the value of d

93.75

Give two different reasons why this is the case

I. The resistance to motion of trailer is unlikely to be constant at 500 N

2. The model does not take into account the unevenness of the road
