Fig. 1.1 depicts a space rocket speeding away from a launch pad. Fig. 1.2 gives a speed-time graph for the first 30 s of the rocket’s flight.
(a)[1]
Describe how the acceleration of the rocket varies between time = 10 s and time = 30 s.
(b)[2]
By drawing a tangent to the graph, determine the acceleration of the rocket at time = 25 s.
(c)[2]
Determine the distance travelled by the rocket between time = 0 and time = 10 s.
