A billiard ball is hit and acquires speed of (2.0m / s) )î.. A second ball, identical to the other, takes a shot and leaves with a speed equal to - (1.0 m / s)î. They graze each other, with the second ball deflecting in the direction of the axis y > 0 at a speed of 1.41m/s. (a) Sketch the physical situation by placing the collision instant at the origin of the x and y axes. (b) What is the magnitude and orientation of the movement of the first ball after the collision? (c) Is the collision elastic? Explain your answer.
