2. Conservation of Linear Momentum See Figure 2. Block 1 of mass m₁ slides from rest along a frictionless ramp from an unknown heighth and then collides with stationary block 2, which has mass m₂ = 3m₁ . The collision is an elastic one. After the collision, block 2 slides into a friction-filled region where the coefficient of kinetic friction is 0.5 and comes to a stop through a distance d = 10 m in that region. (a) What is the height h? (ANSWER: h = 20 m) (b) What is the velocity of block 1 just after the collision? (ANSWER: (-)10 m/s) (If the collision were instead, completely inelastic (that is, the objects stick together, what is the height h?)
