A 140-kg rugby player running east with a speed of 4.00 m/s tackles an 87.5-kg opponent running north with a speed of 4.30 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?
