Perfectly Inelastic Collision of Raindrops

Perfectly Inelastic Collision of Raindrops#

Two raindrops in a cloud collide perfectly inelastically. The first raindrop has a mass of 0.81 g and is travelling with \(\vec{v_1} =\) (-13.7 \(\hat{\imath}\) + 16.8 \(\hat{\jmath}\)) m/s. The second raindrop has a mass of 0.43 g and is travelling with \(\vec{v_2} =\) (19.0 \(\hat{\imath}\) - 1.52 \(\hat{\jmath}\)) m/s.

Part 1#

What is the resulting velocity of the combined raindrop?
