Question

A child rides a bicycle in a circular path with a radius of 2.0 m. The tangential speed of the bicycle is 2.0 m/s. The combined mass of the bicycle and the child is 43 kg. What is the magnitude of the bicycle’s centripetal acceleration?

Answer 1

Angular Momentum = tangent velocity X Radius X Mass

2.0m/s X 2.0 X 43kg

172 m kg / s

Answer 2

86 m/s^2.. hope it will help you
