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 9.9 m/s at an angle of 29 degrees above the horizontal. With some quick research on your smartphone, you know that a typical professional hockey stick weighs 2.7 kg. If the hockey player recoiled with a speed of 0.6 m/s, what is their mass in kg?

1 answer

The mass of the hockey player can be calculated using the equation m = (2.7 kg * 9.9 m/s^2) / (0.6 m/s * sin(29 degrees)). This gives a mass of approximately 48.3 kg.
