Questions
A car runs at a constant speed on a circular track of radius 100 m, taking 62.8 seconds for every circular lap. The average velocity and average speed for each circular lap respectively is
detailed solution
Correct option is C
Distance travelled in one rotation (lap) =2πr∴Average speed=distancetime=2πrt=2×3.14×10062.8=10 m s-1Net displacement in one lap=0Average velocity=net displacement time=0t=0Talk to our academic expert!
