Alok is travelling to a temple on foot. He starts from the base of a mountain and a temple is at distance of
5km from the base and at a vertical height of 500m. He also notes his uniform speed, distance and height
from the base at regular intervals (shown in table). Alok weights 50kg.
Find the kinetic energy in the 500 - 2000 interval.
(b) Find his potential energy at the end of 2000 - 4000 interval
How much work has Alok done against the gravity when he reaches the temple?
(d) State the law of conservation of energy.​
