A ball (A) of mass 1.4kg is moving with a speed of 3.7m/s collides with a 0.55kg ball (B) which is at rest. If Ball A is going 2.3m/s after the collision, what will the velocity of Ball B be after the collision?

If the speed of a particle triples ,by what factor does its kinetic energy increase?

What is the magnitude of the resultant vector round your answer to the nearest tenth
