Question

Ms. Muse shoots a 0.005 toy dart at a toy boat with a plastic sail. The dart sticks to the sail of the boat and begins to move in the opposite direction. What is the final velocity of the boat if the boat was originally traveling toward Ms. Muse at 0.05 m/s, the mass of the boat is 0.42 kg, and the darts original velocity was 57.91 m/s?

Answer 1

0.005 *57.91 - 0.42 * 0.05 = 0.425 * v
