A race car travels on a flat circular track at the maximum possible speed without slipping. If the radius of the track is 39m and the coefficient of friction is 0.73, how long (seconds) does it take the race car to complete 5
A cyclist rides one lap of a circular track at a constant speed so that the riders distance, d meters, from the starting point at any time, t seconds, after starting is: d= (50) - ( 50cos x (pi)t/30, find: (a) the time taken to
A race car track has been constructed with the a bank angle of 32.7° so there is no friction force. The race car track has a curve radius of 394 m. What speeds, for the race cars, has the track been designed to accommodate?
1 a cyclist moving on a circular track of radius 100m completes one revolution in 2 minutes what is his average speed and average velocity in one full revolution. 2 moving with uniform acceleration a body covers150m during 10 sec
