1. A 0.50 kg block, starting at rest, slides down a 30.0° incline with kinetic friction coefficient 0.24 (the figure below). After sliding 82 cm down the incline, it slides across a frictionless horizontal surface and encounters a spring (k = 38 N/m). What is the maximum compression of the spring? and After the compression of part (a), the spring rebounds and shoots the block back up the incline. How far along the incline does the block travel before coming to rest?
2.A crate of mass m1 on a frictionless inclined plane is attached to another crate of mass m2 by a massless rope. The rope passes over an ideal pulley so the mass m2 is suspended in air. The plane is inclined at an angle = 36.9°. Use conservation of energy to find how fast crate m2 is moving after m1 has traveled a distance of 1.4 m along the incline, starting from rest. The mass of m1 is 13.4 kg and the mass of m2 is 18.8 kg.
Any kind of help would be really really appreciated. Thanks
