The small $0\mathrm{.}24-kg$ slider is known to move from position $A$ to position $B$ along the vertical$-$plane slot. Determine $($a$)$ the work done on

the body by its weight and $(b)$ the work done on the body by the spring. The distance $R=0\mathrm{.}97m,$ the spring modulus $k=176\frac{N}{m},$ and

the unstretched length of the spring is $0\mathrm{.}73$ m $.$

Answers:

$($a$)$ Work done on the body by its weight: $,U_g=$

$N*m$

$($b$)$ Work done on the body by the spring: $U_S=$

$N*m$
