Find the mechanical energy lost as a result of collision

Reference no: EM13304908

In an American football game, a 90.6 kg fullback running east with a speed of 5.00 m/s is tackled by a 94.3 kg opponent running north with a speed of 3.03 m/s.

(a) If the collision is perfectly inelastic, calculate the speed and direction of the players just after the tackle.

° (north of east)

(b) Determine the mechanical energy lost as a result of the collision.
