Question

a solid sphere of mass 1 kg rolls on a table with linear speed 2 m/s find its total kinetic energy

Answer 1

Its kinetic energy is 2. As KE =1/2mv square

Answer 2

hii Mac
here is your answer

kinetic energy
$\frac{1}{2} m {v}^{2}$

$\frac{1}{2} \times 1 \times {2}^{2}$

$\frac{1}{2} \times 4$

$kinetic \: energy \: = 2j$

hope it helps
