Question

GPE = 219.52 J Mass = 5.6 kg Find the Height.​

Answer 1

Answer:

Gravitational potential energy = ( m g h )

where m = 1 kg is mass , g = 9.8 m/s2 is acceleration due to gravity and h = 5 m is height above ground

Gravitational potential energy = ( 1 × 9.8 × 5 ) = 49 J

When the mass just before hits the ground, by conservation of energy , all its potential energy is converted to kinetic energy.

Kinetic energy just before hitting the ground = 49 J
