$.$ A $2\mathrm{.}0-$kg block is pushed against a spring comprsssing it $4\mathrm{.}5$ cm$.$ The block leaves the

spring with a speed of $3\mathrm{.}00$ m$/$s$,$ and moves along a frictionless horizontal surface and

then up an incline with slope $=37$ and a coefficient of kinetic friction $($k $=0\mathrm{.}250).$

a$.$ What is the spring constant $?$

b$.$ How far does the object travel up the incline before momentarily stopping?
