Question

A mass of 10kg falls from a height of 50cm. Calculate.

1) velocity of the body

2)kinetic energy of the body when it just reaches the ground.

Does the velocity depends on the mass of the particle? Explain

Answer 1

Answer:

Mass=10 kg

Height = 50 cm =0.5 m

W= mgh

=10*10*0.5

=50 J

Since kinetic energy=potential energy by law of conservation of energy ..

hope it helps you:-)
