# Question

A 1.50-kg mass is placed on the end of a spring that has a spring constant of 175 N/m. The mass– spring sys-tem rests on a frictionless incline that is at an angle of from the horizontal (Fig. 5.31). The system is eased into its equilibrium position, where it stays.

(a) Determine the change in elastic potential energy of the system.

(b) Determine the system’s change in gravitational potential energy.

(a) Determine the change in elastic potential energy of the system.

(b) Determine the system’s change in gravitational potential energy.
