0.5 kg hockey sliding at 2 m/s

1 answer

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.
