if we lift a body of mass 70 g vertically upwards to a height of 10 metre, what is the force required to lift the body

Open in App

Solution

Force required = mass × velocity

m = 70 g = 0.07 kg

g = 9.8 m/s²

f = 0.07 × 9.8
= .686 N

Force required = mass × velocity m = 70 g = 0.07 kg g = 9.8 m/s​2 f = 0.07 × 9.8 = .686 N

Force required = mass × velocity

m = 70 g = 0.07 kg

g = 9.8 m/s²
