(B) The formula for kinetic energy $(KE)$ is given by $KE = \frac{1}{2}mv^2$.Given: Mass $(m)$ = $1\, kg$,Kinetic Energy $(KE)$ = $1\, J$.Substituting the values into the formula: $1 = \frac{1}{2} 	imes 1 	imes v^2$.$v^2 = 2$.$v = \sqrt{2} \approx 1.414\, m/s$.Therefore,the body will have a kinetic energy of $1\, J$ at a speed of approximately $1.414\, m/s$.

At what speed will a body of mass $1\, kg$ have a kinetic energy of $1\, J$ (in $, m/s$)?
