A 85 kg fullback moving east with a speed of 8.0 m/s is tackled by a 100 kg opponent running north at 2.0 m/s. If the collision is perfectly inelastic, calculate each of the following. (a) the velocity of the players just after the tackle 4.76 x Your response differs from the correct answer by more than 10%. Double check your calculations. m/s (b) the kinetic energy lost as a result of the collision ] Can you account for the missing energy?
