In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.
A man of mass 75 kg stands on the floor of a lift. The total mass of the lift and its contents, including the man, is 600 kg.
The lift accelerates vertically upwards at 0.8 m s−2^{-2}−2.
Find the tension in the lift cable.
Find the magnitude of the normal reaction of the lift floor on the man.
