Another question pls help me !!?

Question

2 toy cars A abd B collide and stick togeather on a frictionless surface. Car A has a mass of 1.25kg and a velocity of 2.00m/s east. Car B has a mass of 1.80kg and a velocity of 1.00m/s north.

a) After the collision the magnitude of the total momentum will be Nkg.m/s. The value of N is ??

b)After the collision the direction of the resultant momentum will be n degrees. The value of n is ??

Answer 1

Hi. Just hints, OK. The momentum gets conserved. Always. The 1.25 * 2.0 equals ???. The 1.80 * 1 equals ??? . The total momentum equals ???.
