1.	A body of mass 5kg is taken from a height of 3m to 6m.Calculate the following:(i) Initial potential energy.(ii) Final potential energy.(iii) The change in total potential energy.
Answer» <P>GIVEN Mass = 5 kg Initial Height = 3 m Final height = 6 m To Find Initial Potential ENERGY Final Potential Energy Change in potential energy Solution ● Potential Energy is given by, P = mgh ✭ Initial Potential Energy → P = mgh → P (Initial) = 5 × 10 × 3 → P (Initial) = 150 J ✭ Final Potential Energy → P = mgh → P (Final) = 5 × 10 × 6 → P (Final) = 300 J ✭ Change in Potential Energy → Final - Initial → 300 - 150 → 150 J

To Find

Solution

● Potential Energy is given by, P = mgh

✭ Initial Potential Energy

→ P = mgh

→ P (Initial) = 5 × 10 × 3

→ P (Initial) = 150 J

✭ Final Potential Energy

→ P = mgh

→ P (Final) = 5 × 10 × 6

→ P (Final) = 300 J

✭ Change in Potential Energy

→ Final - Initial

→ 300 - 150

→ 150 J
