$Q-1.$ The $10lb$ cylinder is falling from A with a speed $v_A=10$

$f\frac{t}{s}$ onto the platform. Determine the maximum displacement n the platform, caused by the collision. The spring has an

unstretched length of $1\mathrm{.}75ft$ and is originally kept in

compression by the $1-$ft$-$long cables attached to the platform.

Neglect the mass of the platform and spring and any energy lost

during the collision. $[$use the principle of work and energv$]$
