Question

A mass of 80 kg is moved vertically upwards through a distance of 6 m. If the gravitation
acceleration is 9.8 m/s, then the work done against gravity is
A) 480 J
B) 58.8 J
C) 4,704)
D) 784 J

Answer 1

Answer:

mass = m = 80 kg

height = h = 6m

gravity = g = 9.8 m/s²

work done = mgh

= 80×9.8×6

= 4704 Joules
