Question

BEGINNER'S BOX-1
ves on a circular path of radius Y. It completes one revolution in 40 s. Calculate distance and
displacement in 2 min 20 s.​

Answer 1

Answer:

distance= 22Y

displacement = 2Y

Explanation:

total time = 20*60+20= 140 sec.

40 sec takes for one revolution

in 140sec= 3 and half revolution occur

so distance = 3*2πY+ 2πY/2

= 7πY= 22Y

and displacement in 3 revolution is zero and half revolution is 2Y.
