Question

Calculate the force with which
the body will fall on u.
Also calculate, the kinetic
energy, when body will be at height 6 ft. from ground.
(take g=9.8m/s, mass of
body=62 kg..)

Answer 1

F = mg = 62kg * 9.8N/kg = 607.6N.

d = 6Ft * (1/3.3)m/Ft = 1.82m.

PE = mgh = 62 * 9.8 * 1.82 = 1106 Joules.
