Q1. The diagram shows a helicopter being used to rescue a person from the sea.
(a)
(i)
The mass of the rescued person is 72 kg.
Use the equation in the box to calculate the weight of the rescued person.
gravitational field strength = 10 N/kg
Show clearly how you work out your answer. . .
Weight = .N
An electric motor is used to lift the person up to the helicopter. The motor lifts the person at a constant speed.
State the size of the force, T, in the cable.
Force T = .N
