A particle of mass 0.3 kg subject to a force `F=-kx` with `k=15N//m`. What will be its initial acceleration if it is released from a point 20cm away from the origin?

A

`3 m//s^(2)`

B

`15 m//s^(2)`

C

`5 m//s^(2)`

D

`10 m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
Initial acceleration
`= F/m = ((15)(0.20))/(0.3) = 10 ms^(-2)`
