Answer #1

Convert rpm to radians as its standard unit. 7.18 rpm 7.18 (27)radians per minute -14.36T rad/ minute 0.23933rad/:s The angular velocity is 0.23933T rad/s. Use the following formula to find the velocity of the child: Here, r is the radius and wis the angular velocity. v 4.65m (0.239337 rad/ s) -3.49 m/s
