Academics

Q1. In an American football game, an 89.3 kg fullback running east with a speed of 5.09 m/s is tackled by a 95.8 kg opponent running north with a speed of 3.01 m/s.

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

Q2. 26 g of copper pellets are removed from a 300 degree Celsius oven and straight away dropped into 116 mL of water at 25 degree Celsius in an insulated cup. What will the new water temperature be?
