Jumping Off a Raft

A raft of mass 180kg carries two swimmers of 50 kg and 80 kg. The raft is initially at rest but the swimmers dive off opposite ends each at 3 m/s.

With what velocity and in what direction does to raft start to move?

Solution Preview

This is a problem related to momentum and its conservation.

Momentum(p)= Mass * Velocity and in a closed system it is conserved i.e. Initial momentum=Final momentum.

Now for our case, since ...

Solution Summary

Momentum(p)= Mass * Velocity and in a closed system it is conserved i.e. Initial momentum=Final momentum.
