Given - Mass and velocity

Find - Kinetic energy

Solution - Kinetic energy is calculated by the formula - 1/2*m*v². Keep the values in formula to find the kinetic energy.

K.E. =  \frac{1}{2}  \times 6.8 \times  {6}^{2}

Taking square and performing division

K.E. = 3.4 \times 36

Performing multiplication

K.E. = 122.4 Joules

Hence, kinetic energy of the block is approximately 122.4 Joules.
