A $2\mathrm{.}00$ kg object is initially held at rest upon an incline of $65\mathrm{.}0.$ The coefficient of kinetic friction between the mass and the incline is $0\mathrm{.}400.$ The mass is released at t $=0.$ a$)$ What is the Net force acting on the mass as it slides down the incline? b$)$ What is the acceleration of the mass as it slides down the incline? c$)$ What is the speed of the mass after sliding $2\mathrm{.}00$ m$?$
