A 1.8-kg block, initially at rest, slides down a frictionless ramp that is angled at 35º to the horizontal. At a point 0.45 m down the slope it collides with and sticks to a stationary block of mass 1.1 kg. The blocks then continue another 0.88 m down the ramp. How long does the whole event take? (For those of you wondering how a block is stationary on a frictionless ramp, it was projected up the ramp from below so it had no speed at the time of impact.)
