What is the kenetic energy of a 2.0 kg ball moving at 4.0 m/s? KE = 1/2 m.v raised to the second power

1 answer

To calculate the kinetic energy, you will use the formula KE = 1/2 m * v^2.

Given that the mass (m) of the ball is 2.0 kg and the velocity (v) is 4.0 m/s, substitute these values into the formula:

KE = 1/2 * 2.0 kg * (4.0 m/s)^2

Simplifying the equation:

KE = 1/2 * 2.0 kg * 16.0 m^2/s^2

KE = 16.0 kg m^2/s^2

Therefore, the kinetic energy of the 2.0 kg ball moving at 4.0 m/s is 16.0 Joules (J).
