A 190-kg rugby player running east with a speed of 4.00 m/s tackles a 99.0-kg opponent running north with a speed of 3.90 m/s. Assume the tackle is a perfectly inelastic collision. (Assume that the +x axis points towards the east and the +y axis points towards the north.)
(a) What is the velocity of the players immediately after the tackle?
| magnitude | m/s |
| direction | ° counterclockwise from the +x axis |
(b) What is the amount of mechanical energy lost during the
collision?

(non calculus physics) A college fullback weighing 100 kg is running north at a speed of 4.5 m/s when he is tackled by a 110 kg linebacker running east at 3.5 m/s. Assume the collision is perfectly inelastic. Find the velocity of the players just after the tackle. Find the kinetic energy lost as a result of the collision. How do you account for this apparently “lost” energy?
