Question

A particle is moving along a circle such that it
completes one revolution in 40 seconds. In 2
minutes 20 seconds, the ratio
displacement
is
distance​

Answer 1

Step-by-step explanation:

GIVEN- TIME-40 SEC

NO OF REVOLUTION-1

TIME-2 MIN 20 SEC=140SEC

SOLVE- displacement: distance

SOLUTION- 1revolution=40sec

? =140sec

140/40 =3 1/2 rev

3 1/2rev= distance=7/2

displacement=1/2 rev

RATIO=1/2:7/2
