2a) Mass 1 is moving at 6 m/s in the +x direction and it collides in a perfectly elastically with mass 2 of 2 kg moving at 15 m/s in the -x direction. They collide for 0.3 seconds, and the average force on mass 1 is 148 N in the -x direction. What is the mass of mass 1 in kg?

2b) Mass 1 is moving at 3 m/s in the +x direction and it collides inelastically with mass 2 of 18 kg moving at 14 m/s in the + x direction. 128 Joules of KE is lost in this collision. What is the average force on mass 1 if the collision takes place in 0.1 seconds? Answer in Newtons.

Please note that part A and part B have different values.
