A 1.5okg ball whose velocity is 8mls southward collides with a 2kg ball traveling along the same path with a velocity of 3mls southward.if the velocity of the 2kg ball is 7.29mls southward after impact.what is the velocity of the 1.50kgball?
momentum before = 1.5*8 + 2*3
momentum after = 1.5*x + 2*7.29
