Kinetic energy = 1/2 (mass) (speed squared)

KE = 1/2 (70kg) (2m/s)^2

KE = (35 kg) (4 m^2/s^2)

KE = (140) kg-m^2/s^2

That's 140 Newton-meter

or

140 Joules

The kinetic energy is 140 joules

The parameters given in the question are

mass= 70 kg

velocity= 2m/s

Kinetic energy= 1/2mv²

= 1/2 × 70 × 2²

= 0.5 × 70 × 4

= 140 joules

Hence the kinetic energy is 140 joules
