Calculate the acceleration of the block and trolly system shown in the figure. The coefficient of kinetic friction between the trolly and the surface is 0.05. ( $\displaystyle g=10 \mathrm{~m} / \mathrm{s}^2$, mass of the string is negligible and no other friction exists).
Official answer
(4)
$\displaystyle 1.25 \mathrm{~m} / \mathrm{s}^2$
