Question

an object of mass 12 KG is moving with kinetic energy 726 t calculate its velocity​

Answer 1

Answer:

v= 11m/s

Explanation:

$k.e = \frac{1}{2} m {v}^{2} \\ 726 = \frac{1}{2} (12) {v}^{2} \\ 726 = 6 {v}^{2} \\ \frac{726}{6} = {v}^{2} \\ 121 = {v}^{2} \\ \sqrt{ {v}^{2} } = \sqrt{121} \\ v = 11 \frac{m}{s}$
