A flywheel with a diameter of 1.00 m and initially rotating at an angular speed of 500 revolutions per minute (rpm) changes its angular speed at 1000 rpm after 20.0 s. Assuming a constant angular acceleration, find a. its value in (rad/s?), b. the angle through which the flywheel turns in moving from 500 rpm to 1000 rpm. (in degrees) c. the acceleration of any point on the rim (m/s?). A 150-g ball at the end of a string is revolving uniformly in a horizontal circle of radius 0.600 m. The ball makes 2.00 revolutions in a second. Find its a. period of revolution (s). b. tangential speed (m/s) C. centripetal acceleration (m/s?). d. centripetal force (N)
