C+0 -1 points Hawk PSE 1 P.059 My Notes Ask Your Teacher A mass (m 795 g) rests on a 63.0 ncline, where it is attached to one end of a spring, also resting on the incline as shown in the figure below. The other end of the then released. The coefficient of kinetic fric between held in place so that the spring is unstretched. The mass is spring is fixed. The mass is on the surface and the mass is 0.0700, and the spring constant is 115 N/m. Find the maximum compression of the spring. Cm 63 Need Help?

Explanation / Answer

work done by gravity

mg*x sin theta

work dine by spring = -1/2*kx^2

work done by friction = mu*mg*cos theta

0.755 * 9.8 * sin 63 *x - 115/2 * x^2 - 0.07 * 0.755 * g * cos63 = 0

6.59 x - 57.5 x^2 - 0.235x = 0

6.355x - 57.5x^2 = 0

x = 9.048 m
