Question

A particle moves on a circular path of radius 'r', It completes one revolution in 40 s. Calculate distance and displacement in 2 min 20 s.​

Answer 1

Answer:

Explanation:let r=r

Circumference =2pi*r

=2*22/7*r=44/7r

Distance cover in 40s=44/7r

Distance cover in 1s=44/7r÷40

Distance cover in 2min20s(140s)=44/7r÷40*140=22r
