An object is attched to the bottom of a light vertical spring and set vibrating. The maximum speed of the object is `15cm//s` and the period is `628` milli seconds. The amplitude of the motion in centimetres is

A

`3.0`

B

`2.0`

C

`1.5`

D

`1.0`

Text Solution

Verified by Experts

The correct Answer is:
C
`v_(max)=Aomega=A(2pi)/(T)`
`implies 15=Axx(2pi)/(628xx10^(-3))`
`implies A=1.5cm`.
