a block of wood of mass m1= 1 kg slides to the right on a frictionless horizontal table with a speed of 30 m/s. it collides with a second piece of wood of mass m2 = 2kg which is stationary at position X. The collission is completely inelastic. after the collision, the wood slides across a rough horizontal surface (friction component is .3) from B to C for distance 10m. After position C the surface becomes smooth and the wood collides with a spring constnat of k=30.00 N/m/
A) how much is the spring compressed by the wood?
B) at what locations along the horizontal plane is mass M2 stationary?
