2. Inelastic collision. In a collision experiment, block A starts from rest at an initial height of 2.00 meters above the ground, and gains speed by sliding down a frictionless ramp towards block B. Block B starts from an initial height of 4.00 meters and slides down from another frictionless ramp towards block A. Block A has twice the mass of block B. They are released at different times so that they collide in the middle on flat ground (at the dashed line). 2 m A B 4 m Given that the two blocks stick together after the collision (they have sticky tape on the sides), find the velocity of the combined object just after the collision. 2.
