a mass of 200 kg travels down a frictionless roller coaster from a height of 50 m. When it reaches the level ground (height 0 m) it encounters an unstretched horizontal spring with spring constant 10,000 N/m. As the mass comes to a rest how far does it compress the spring?
just before touching the spring Kinetic energy = potential energy at top = 200*9.8*50
on touching the spring this energy gets converted into potential energy of spring
so 0.5*10000*x^2 = 200*9.8*50
=> x = 4.43 m

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...
