FRQ Prompt 1: (Questions 1-9) Spacecraft A and B are flying parallel to each other through space and are next to each other at time t = 0. For the interval 0 < t < 6 s, spacecraft A’s velocity vA and spacecraft B’s velocity vB as functions of t are given by the equations vA(t) = t2 - 5t + 20 and vB(t) = t2 + 3t + 10, respectively, where both velocities are in units of meters per second. At t = 6 s, the spacecraft both turn off their engines and travel at a constant speed.

  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.
