(a)[1]
Calculate the weight of the man.
(b(i))[2]
The lift accelerates upwards at a constant rate of $0.50\,\text{m s}^{-2}$. Calculate the resultant upward force on the man.
(b(ii))[1]
Calculate the force exerted on the man by the floor of the lift.
(c)[3]
The lift moves upwards uniformly from rest for $4.0\,\text{s}$ and then slows uniformly to rest over the next $4.0\,\text{s}$. The total distance covered is $8.0\,\text{m}$. On Fig. 2.2, sketch the distance-time graph that represents this journey.
