Time taken from to to
length path
speed(maximum) along the circular path of the car
Time: to and to
is the maximum speed
Time : to to
Hence, total time taken by the car
A racing car travels on a track ABCDEFA. ABC is a circular arc of radius 2 R. CD and FA are straight paths of length R and DEF is a circular arc of radius R = 100 m. The coefficient of friction on the road is μ = 0.1. The maximum speed of the car is 50 m/s. Find the minimum time for completing one round.
