Question

What is a cars tangential speed when its 700kg and makes one lap around a 48 m radius in 10 seconds

Answer 1

Answer: 30 m/s

Explanation: Using the equation V=(2*pi*r)/T, as the perimeter of the circle divided by time, we get V=(2*pi*48m)/10sec=30.1592847. Rounding this figure gives a tangential velocity of 30 m/s.
