(a)[2]
Calculate the rocket’s acceleration.
(b(i))[1]
On Fig. 1.1, draw the graph showing the rocket’s motion during the first 8.0 s.
(b(ii))[2]
Use the graph to work out the rocket’s height at 8.0 s.
(b(iii))[3]
From time = 8.0 s to time = 20.0 s, the rocket moves faster and faster but with a smaller and smaller acceleration. From time = 20.0 s to time = 25.0 s, it travels at a constant speed of less than 200 m/s. On Fig. 1.1, draw the graph for this motion.
