Expert 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
