What is the kinetic energy of the hockey?
The kinetic energy can be calculated using the formula:
KE = 1/2 * m * v^2
where KE is kinetic energy, m is the mass of the object, and v is the velocity of the object.
Substituting the given values, we get:
KE = 1/2 * 0.5 kg * (2 m/s)^2
KE = 1/2 * 0.5 kg * 4 m^2/s^2
KE = 1 J (Joule)
Therefore, the kinetic energy of the hockey is 1 Joule.
