Question

An object has a kinetic energy of $14J$ and a mass of $17kg$ . How fast is the object moving?

Answer 1

The kinetic energy is given as

$K.E.=\frac{1}{2}m{v}^2$

By substituting the values in the above equation we get

$v=\sqrt{\frac{2\times 14}{17}}$

Hence the velocity of the body is

$1.28m/s$
