Problem

0.50\,\text{kg}

block is connected to a horizontal spring of force constant

200\,\text{N\,m}^{-1}

. At

t = 0

it passes through the equilibrium position moving in the positive direction with speed

0.40\,\text{m\,s}^{-1}

. a. (i) Find its displacement at

t = 0.10\,\text{s}

. b. (ii) Find its velocity at

t = 0.10\,\text{s}

. c. (iii) Find its acceleration at

t = 0.10\,\text{s}
