(a) Maximum acceleration
${A_{\max }} = a{\omega ^2}$
${A_{\max }} = a{\omega ^2}$
$= \frac{{a \times 4{\pi ^2}}}{{{T^2}}}$
$ = \frac{{1 \times 4 \times {{(3.14)}^2}}}{{0.2 \times 0.2}}$
${F_{\max }} = m \times {A_{\max }}$
$= \frac{{0.1 \times 4 \times {{(3.14)}^2}}}{{0.2 \times 0.2}}$
$= 98.596\;N$
