Question

How much work is done when a mass of 3 kg (weighing 30 N)
is lifted vertically through 6 m?.


A hiker climbs a hill 300 m high. If she has a mass of 50 kg
calculate the work she does in lifting her body to the top of the
hill.
work = force * distance = 30 N * 6 m
... answer is in Joules


work = m g h = 50 * 9.8 * 300
Thank you
