1. Two identical curling stones of mass 17 kg collide. The first stone hits the stationary second stone with a constant velocity of 6.0 m/s [N]. If the velocity of the first stone is 2 m/s [N 20°W] after the collision, find the velocity of the second stone after the collision. Assume that effects due to friction are negligible. 2. A block of mass 5 kg is placed next to a spring with a spring constant of 350 N/m on a flat, horizontal, frictionless surface. The block is then pushed against the spring and compresses it a distance of 0.05 m. Find the acceleration of the block the instant it is released. PS: Answer both questions by hand on paper with step by step format, add diagrams and detailed side notes for a better understanding

1.A cue ball (mass = 0.165 kg) is at rest on a frictionless pool table. The ball is hit dead center by a pool stick, which applies an impulse of + 1.50 N's to the ball. The ball then slides along the table and makes an elastic head-on collision with a second ball of equal mass that is initially at rest. Find the velocity of the second ball just after it is struck.
