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.
