a 2.0 kg mass moves along a frictionless horizontal surface at a speed of 5.0 m/s. The mass encounters a 30 degree inclined surface with a constant friction force of 1.5 N. At 1 m high (vertical) the surface levels off and is again frictionless. the mass then encounters a spring with k=10 N/m a) how far is the spring compressed after the mass comes to rest? b) how far down the inclined plane will the mass move after bouncing...
