A 4.00 kg ball traveling North with a momentum of 11.2 kg.m/s collides with a 6.0 kg ball traveling West with a momentum of 18 kg.m/s. The two balls stick together and head off as one. What is the momentum of the combined masses? What is the velocity of the combined masses?

Solutions

Expert Solution

In order to find the final momentum and velocity of the combined balls wr have to use the conservation of linear momentum in x and y direction.
