Perfectly Inelastic Collision of Raindrops#

Two raindrops in a cloud collide perfectly inelastically. The first raindrop has a mass of 0.73 g and is travelling with \(\vec{v_1} =\) ( \(\hat{\imath}\) \(\hat{\jmath}\)) m/s. The second raindrop has a mass of 0.4 g and is travelling with \(\vec{v_2} =\) ( \(\hat{\imath}\) \(\hat{\jmath}\)) m/s.

Part 1#

What is the resulting velocity of the combined raindrop?

Answer Section#

  • -7.5\(\hat{\imath}\) + 4.5\(\hat{\jmath}\) m/s

  • -4.8\(\hat{\imath}\) + 2.9\(\hat{\jmath}\) m/s

  • -14.0\(\hat{\imath}\) + 8.2\(\hat{\jmath}\) m/s

  • -3.1\(\hat{\imath}\) + 1.8\(\hat{\jmath}\) m/s

  • -4.9\(\hat{\imath}\) + 9.3\(\hat{\jmath}\) m/s

  • -1.9\(\hat{\imath}\) + 3.6\(\hat{\jmath}\) m/s
