a) AB- ball rising to max height
BC- ball falling to ground
CDE- ball rebouncing/ changing velocity from +ve to –ve
b) Acceleration = gradient = 19.8 = 9.9 m/s2
c) Displacement = area
= ½ x 2 x 19.8 = 19.8m
d) Upon hitting the ground the ball looses some energy.

(Solved)
An object moving at 26m/s starts to accelerate at 2m/s² so that its velocity becomes 48m/s. Find
i) The distance moved during this acceleration.
ii) The object is now braked so that it comes to rest in a time of 12 seconds. Find the braking force if its mass was 27000g.
