Question

Motorcycle is taking round with the constant speed along a circular path of radius 100 m and completes a revolution in 62.8 second what is the speed of the motor cycle and what is average

Answer 1

Distance travelled by the motorcycle is 2$\pi$r where r is the radius. In this case r=100 hence distance=200$\pi$

Speed=D/t

=(200$\pi$)/62.8

=10m/sec (assuming $\pi$=3.14)

Average speed=Total distance/Total time taken

which in this case is also equal to 10m/sec
