Answer:
2.1 sec
Explanation:
a car runs around a curve of radius 10meter at a constant speed of 10m/s .consider the time interval for which the carcovers a curve of 120°arc
Distance to be covered = (120/360) * 2 π R
= (1/3) * 2 * (22/7) * 10
= 440/21 m
Speed = 10 m/s
Time = (440/21)/10 = 44/21 = 2.1 sec
