The first block is again brought to rest at equilibrium. An identical block is launched up into the first block. The new block is moving with a speed of v = 5.0 m/s when it collides with and sticks to the original block. Calculate the maximum compression of the spring, in cm, after the collision of the two blocks.

A truck begins at rest and moves with a constant acceleration of 2 m/s2 for a period of 10 s. It then cruises at a constant speed for an additional 10 s before slowing to a stop, again with acceleration of 2 m/s2. Which graph best represents the motion of the truck? Velocity-time graph a increases linearly from zero, stays constant for a period, then decreases linearly back to zero. Velocity-time graph b rises quickly with slight curvature, levels off briefly, then curves downward to zero. Velocity-time graph c rises and levels off, then decreases more gradually with a curved decline to zero.Velocity-time graph d forms a single smooth arch, rising from zero to a peak and then returning symmetrically to zero.
