A frustrated hockey player, at rest on a frictionless ice rink, throws his stick into the crowd. Since you don't normally go to hockey games, you decide to turn this into a physics problem and calculate the mass of this player. You observe that the stick is thrown with a speed 9.8 m/s at an angle of 38.1 degrees above the horizontal. With some quick research on your smartphone, you know that a typical professional hockey stick weighs 2.4 kg. If the hockey player recoiled with a speed of 1.1 m/s, what is their mass in kg? 16.83 kg 18.51 kg 13.19 kg O 1.72 kg
