Perfectly Inelastic Collision of Raindrops#

Two raindrops in a cloud collide perfectly inelastically. The first raindrop has a mass of 0.42 g and is travelling with \(\vec{v_1} =\) (1.31 \(\hat{\imath}\) + 6.28 \(\hat{\jmath}\)) m/s. The second raindrop has a mass of 0.69 g and is travelling with \(\vec{v_2} =\) (-15.0 \(\hat{\imath}\) - 13.3 \(\hat{\jmath}\)) m/s.

Part 1#

What is the resulting velocity of the combined raindrop?

Answer Section#

  • -23.0\(\hat{\imath}\) - 16.0\(\hat{\jmath}\) m/s

  • -8.8\(\hat{\imath}\) - 5.9\(\hat{\jmath}\) m/s

  • -14.0\(\hat{\imath}\) - 9.5\(\hat{\jmath}\) m/s

  • -5.4\(\hat{\imath}\) - 3.6\(\hat{\jmath}\) m/s

  • 24.0\(\hat{\imath}\) + 26.0\(\hat{\jmath}\) m/s

  • 9.8\(\hat{\imath}\) + 11.0\(\hat{\jmath}\) m/s
