What is the change in the total kinetic energy of two balls

Reference no: EM13322544

A ball with a mass of 0.620kg is initially at rest. It is struck by a second ball having a mass of 0.405kg , initially moving with a velocity of 0.260m/s toward the right along the x axis. After the collision, the 0.405kg ball has a velocity of 0.210m/s at an angle of 35.9%u2218 above the x axis in the first quadrant. Both balls move on a frictionless, horizontal surface.

What is the magnitude of the velocity of the 0.620kg ball after the collision?

What is the direction of the velocity of the 0.620kg ball after the collision?

What is the change in the total kinetic energy of the two balls as a result of the collision?
