Question

A motorcycle is traveling about a circle with radius of 15meters. If the coefficient of friction between the tires and the track is 0.76, how many laps can the motorcycle complete in one minute? (N o t e: Friction between the tires and the road enables a vehicle to turn)

Answer 1

max velcity=v

v^2/r=mu*g

solve for v, max velocity

then, laps=velocity*time/2PIr

watch units, time has to be in the same units velocity is using.
