A particle of mass 0.3 kg is subjected to a force F = kx with k = 15 N – m-1. What will be its initial acceleration if it is released from a point 20 cm away from the origin?

A

3 ms-2

B

15 ms-2

C

5 ms-2

D

10 ms-2

Answer

10 ms-2

Explanation

Solution

a = kxm=15(0.2)0.3=10ms2\frac{kx}{m} = \frac{15(0.2)}{0.3} = 10ms^{- 2}.
