Question

A body of mass 5 kg is falling freely from a height
hm. What is the amount of total energy at any
point of fall?​

Answer 1

Answer:

The body of 5kg is at a height of 5m. At a height of 5m above geound, it has

Potential energy of body= 5kg×10m/s²×5m = 250 Joule

Since gravity is a conservative force, if we neglect, air friction, the energy of body at any time during the fall would be 250 Joule.

Energy at any instant of time = potential energy at the height at which it is at that instant of time + kinetic energy it has gained at the cost of potential energy in falling through the height= 250 Joule.

Explanation:

Answer 2

Answer:

U = mgh

so

total energy = 5×9.8×h

U =49h joules

hope it helps you dear.......
