Question

A particle is released from a height h , At a certain height; its kinetic enegy is two times its potential energy. Height and speed of the particle at that instant are, h 3 , 2 g h 3, h 3 , 2 g h 3, 2 h 3 2 g h 3, h 3 , 2 g h

MARKS App · Accepted Answer

Total mechanical energy= m g h As, K E P E = 2 1 K E = 2 3 m g h and P E = 1 3 m g h Height from the ground at this instant, h , = h 3 and speed of the particle at this instant, v = 2 g h - h ′ = 2 g 2 h 3 = 2 g h 3
