Q1. A flywheel having constant angular acceleration requires 4.60 to rotate through 170. Its angular velocity at the end of this time is 109. Find out the angular velocity at the beginning of the 4.60 interval; the angular acceleration of the flywheel.

Q2. A chair of weight 120 N is sitting on the horizontal floor; the floor is not frictionless. You push on the chair with a force = 43 N that is directed at an angle of 39.0 below the horizontal and the chair slides along the floor.

Q3. Two particles with masses 6m and 3m are moving toward each other along the x axis with the same initial speeds vi. The particle with mass 6m is travelling to the left, and particle 3m is travelling to the right. They undergo a head-on elastic collision and each rebound along the same line as it approached. Discover the final speeds of the particles.
