Object 1 (mass=5.5 kg) traveling in the +x direction at a speed of 12.40m/s undergoes an inelastic collision with Object 2 (mass=4.80kg) which is at rest. Object two flies off at a speed of 7.80m/s and an angle θ2=32.4 °. It is possible that Object 1 travels back and to the left, though it is not possible for it to travel in the -y direction.
A)What is the total momentum in x direction after the collision?
B) What is the momentum of Object 1 in the y direction after the collision
C) What is the speed of Object 1 after the collision?
D) What is the angle θ1 in degrees?
