An ice fisherman removes an 8-kg block of ice
from a local pond he plans to use for fishing.
The block is at rest on the surface of the pond
when a 70-kg sledder moving at a speed of 22
m/s collides with the brick of ice. After the
collision, the sledder and the block of ice move
forward as one. Calculate the final speed that
they are travelling at

Respuesta :

The final speed that they are travelling at will be 19.74 m/sec. Apply law of conservation of momentum principle in given problem.

What is the law of conservation of linear momentum?

According to the law of conservation of linear momentum before the collision is equal to the momentum after the collision. These laws state that about how momentum gets conserved.

Apply law of conservation of momentum principle;

m₁v₁+m₂v₂=(m₁+m₂)V

70 kg×22 m/s+8 kg×0=(70+8) kg*V

1540 kg m/s=78 kg × V

V=7.5m/s

Hence,the final speed that they are travelling at will be 19.74 m/sec
