Answer:

The kinetic energy of a 4 kg mass moving at 3 m/s is 18 joules.

Step-by-step explanation:

The kinetic energy (KE) of an object is calculated using the following formula: (image inserted)

Where:

KE: is the kinetic energy

m: is the mass of the object

v: is the velocity of the object

In your case, the mass (m) is 4 kg, and the velocity (v) is 3 m/s. Plugging these values into the formula.

The unit of kinetic energy is the joule (J), which is equivalent to a kg m^2/s^2. So:

KE = 18 J
