Question

Calculate the kinetic energy for a body of mass 5 Kg moving with a velocity 4m/s.​

Answer 1

Answer:

$kinetic \: energy = 40j$

Explanation:

$k = \frac{1}{2} m \: {v}^{2} \\ = \frac{1}{2} \times 5 \times {4}^{2} \\ = \frac{1}{2} \times 5 \times 16 \\ = 1 \times 5 \times 8 \\ \\ k = 40j$
