To calculate the kinetic energy (Ek) of the object with a mass (m) of 10 kg and velocity (V) of 100 km/h, we first need to convert the velocity from km/h to m/s.

1 km/h is equal to 0.2778 m/s. Therefore, 100 km/h is equal to 27.78 m/s.

The formula for calculating kinetic energy is
Ek = 0.5 m V^2

Ek = 0.5 10 kg (27.78 m/s)^
Ek = 0.5 10 kg 771.84 m^2/s^
Ek = 3859.2 Joules

Therefore, the kinetic energy of the object is 3859.2 Joules.
