A spring with a stiffness constant k = 55 N/m has a natural length of 0.55 m. Is is attached to the top of an incline that makes a 30 degree angle with the horizontal. The incline is 2.4 m long. A mass of 2 kg is attached to the spring, causing it to be stretched down the incline. How far down the incline does the end of the spring rest?
0.746 m
0.354 m
0.646 m
0.55 m
1.85 m
A mass, M, is released from rest on an incline that makes a 40 degree angle with the horizontal. In 5 seconds, the mass is observed to have gone a distance of 2 m. What is the coefficient of kinetic friction between the mass and the surface of the incline?

0.7
0.86
1.2
2.55
