Physics

A 2.0-kg ball moving at 10 m/s makes an off-center collisionwith a 3.0-kg ball that is initially at rest. After the collision,the 2.0-kg ball is deflected at an angle of 30° from its originaldirection of motion and the 3.0-kg ball is moving at 4.0 m/s. Findthe speed of the 2.0-kg ball and the direction of the 3.0-kg ballafter the collision.
Hint: sin2θ + cos2θ = 1.

speed of 2.0-kg ball  m/s
direction of 3.0-kg ball  ° from original direction of motion
