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

1.	A particle of mass 0.3 kg is subjected to a force F=-kx with k=15N//m. What will be its initial acceleration if it is released from a point 20 cm away from th origin?
Answer» `5m//s^(2)` `10M//^(2)` `3m//s^(2)` `15m//s^(2)` Solution :`F= -kx`, where `K= 15N//m and x=0.2m` `THEREFORE \|F\|= 15xx0.2=3N` `therefore ` Acceleration `= (F)/(m) =(3)/(0.3)= 10m//s^(2)`
