A particle of mass 0.3 kg is subjected to a force $F = - k x$ with $k = 15 \frac{N}{m}$ . What will be the magnitude of its initial acceleration ( $i n \frac{m}{s^{2}}$ ) if it is released from a point x=20 cm from its equilibrium position?

Solution

Assuming the direction of compression as negative,

$F = - k x = m a \Rightarrow a = \frac{- 15 (0.2)}{0.3} = - 10 m / s^{2}$
