Question Number 46144 by Rio Michael last updated on 21/Oct/18
 Object A is in motion.A moves at a velocity of   12ms^(−2)  and B is still(not moving).If A collides with B.  a) Calculate the velocity at which B will move if it has mass  of 70kg. and A has mass of 60kg.  b) the momentum after collision.  c) state the principle you applied in a) and b) above
