Fig. 1.1 shows a student moving downhill in an unpowered vehicle.
Fig. 1.2 gives the section of the speed-time graph for the vehicle as it goes down the hill.
(a(i))[1]
State how the graph indicates that the acceleration is constant between A and B.
(a(ii))[2]
Calculate the acceleration for the interval between A and B.
(a(iii))[1]
Describe the way the acceleration changes from B to C.
(b)[4]
Use Fig. 1.2 to estimate the distance covered by the vehicle during the first 10 s from the graph.
