Fill in the masses of A and B, their starting velocities (B has only zero or negative velocity in this simulation), the angles at which they are moving (relative to the horizontal line of centres) and the coefficient of restitution. Press Submit each time.
Press Move Masses.
Calculate the velocities for the masses after the collision.
If you want to see the correct velocities press Show Answers.
Press Reset to repeat the simulation with different masses, velocities, angles and coefficient of restitution.
