Question

A cyclist moving on a cellular track of radius 70 m , complete one revoluntion in 4 minute what is average speed and velocity innone full revolution

Answer 1

Explanation:

Given radius(r)=70m

So,diameter(d)=2r=2×70=140m

Distance=140m

displacement=70m

time=4min

Now,

Average speed=total distance/total time

=140/4

=35m/s

Average velocity=total displacement/total time

=70/4

=17.5m/s

Therefore,

Average speed=35m/s

Average velocity=17.5m/s
