Question

Find the gravitational potential energy of 1 kg mass kept at a height of 5 m above the ground and also find the kinetic energy when it falls and hits the ground . Take g = 10 m/a
ANSWER CORRECTLY...... OKK

Answer 1

Gravitational potential energy = 50 J

Given:

Mass of object = 1 kg

Height = 5 m

Gravitational acceleration = 10 m/s²

Find:

Gravitational potential energy

Computation:

Gravitational potential energy = mgh

Gravitational potential energy = (1)(5)(10)

Gravitational potential energy = 50 J

Answer 2

Answer:

50 J,50J

Explanation:

Mass= m = 1kg

Height =h = 5m

Gravitational potential energy = mgh = 1 × 10 × 5 = 50J

K.E = 50 J {kinetic energy of the object on hitting the ground = U}
