Question

5. An object of mass 1 kg travelling in a straight line with a velocity
of 10 m s' collides with, and sticks to, a stationary wooden
block of mass 5 kg. Then they both move off together in the
same straight line. Calculate the total momentum just before
the impact and just after the impact. Also, calculate the velocity
of the combined object.
