(a(i))[1]
State the meaning of mass.
(a(ii))[1]
State the meaning of weight.
(b)[3]
Calculate the acceleration of the parachutist when the air resistance is $200\,\text{N}$.
(c(i))[4]
Draw, on Fig. 9.2, the speed-time graph for the parachutist.
(c(ii))[2]
Calculate the average deceleration of the parachutist from $t = 40\,\text{s}$ to $t = 44\,\text{s}$.
(d(i))[1]
Explain, in terms of the forces involved, why the parachutist reaches a terminal velocity at $t = 30\,\text{s}$.
(d(ii))[2]
Explain, in terms of the forces involved, why the parachutist decelerates when the parachute opens.
(d(iii))[1]
Explain why the second terminal velocity, after the parachute opens, is lower than the first.
