Question

a ball of mass 5kg thrown upwards reaches the maximum height of 3m. calculate the work done by force of gravity during this vertical displacement​

Answer 1

Answer:

-147 J

Explanation:

Given

mass,m = 5 kg

Vertical displacement if ball , S = 3m

acceleration due to gravity, g = 9.8 m/s²

Force, F = mg = 49 N

Since the force and the displacement of the ball are in opposite directions, work done by the force of gravity,

Work = - F * S

= - 49 * 3

= - 147 J
