Question

A 50 kg man stands on the surface of a frozen pond. In order to get to the side of the pond he throws his 1 kg shoes at a speed of 10 m/s. After that what’s the speed of the man? ( neglect all frictions)

Answer 1

As per law of conservation of momentum

1 × 10 = 50× v

v = 1/5 m/S

Or

20 cm/s
