Physics

A ball with a mass of 0.615 kg is initially at rest. It isstruck by a second ball having a mass of 0.380 kg , initiallymoving with a velocity of 0.260 m/s toward the right along the xaxis. After the collision, the 0.380 kg ball has a velocity of0.230 m/s at an angle of 37.4 ∘ above the x axis in the firstquadrant. Both balls move on a frictionless, horizontalsurface.

What is the magnitude of the velocity of the 0.615 kg ball afterthe collision?

What is the direction of the velocity of the 0.615 kg ball afterthe collision?

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