K= 1/2mv^2
K=1/2(210kg)(10.5 m/s)^2


unit:

Explanation:

The expression given in the question which is

Is the expression for the kinetic energy stored in a system and it is measured in Joules

From the expression we can see that

mass m=210 kg

velocity v= 10.5 m/s

Substituting as seen in the question we have the kinetic energy as

hence the energy stored is 11577.25 Joules
