Name___________________________________ Circular Motion, Centripetal Force / acceleration 1) A 1.5 kg steel ball is swung in a horizontal circle of radius 0.75 meters. A student times ten revolutions with a stopwatch and gets a time of 8.5 seconds. a) Determine the tangential/translational velocity of the steel ball. b) Determine the angular velocity of the ball. c) Determine the centripetal acceleration of the ball. d) Determine the tension in the string. e) If the string breaks when the ball is in position A, where does the ball go?

2) The steel ball from problem #1 is now swung in a vertical loop at the same constant speed. Determine: a) the tension in the string at the highest point b) the tension in the string at the lowest point c) the tension in the string at a point when the string is horizontal to the ground
3) Mandy is sitting in her tire swing at the end of a 2.5 meter long rope. She starts her swing when it makes an angle of 35 degrees with the vertical. If Mandy and the tire
