(a)[1]
Calculate the total weight of the man and child.
(b(i))[2]
Calculate the cable tension while the initial acceleration is $0.570\,\text{m s}^{-2}$.
(b(ii))[1]
Calculate the cable tension while the man and child move at constant velocity of $2.00\,\text{m s}^{-1}$.
(c)[2]
During the final deceleration, the cable tension is $1240\,\text{N}$. Calculate this deceleration.
(d(i).1)[1]
Calculate the duration for which the man and child are accelerating uniformly.
(d(i).2)[1]
Calculate the period over which the man and child move with uniform deceleration.
(d(ii))[2]
The duration of constant velocity is $20\,\text{s}$. On Fig. 3.2, sketch a graph showing how the velocity of the man and child varies with time throughout the whole lifting process.
