A body of mass 400 g is moving along a smooth surface at a velocity of 10 m s–1 east. It strikes a body of mass 650 g, initially at rest, and then the 400 g body moves at a velocity of 8 m s–1 in a direction E35°N. What is the velocity of the 650 g object?

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude
