(B) Given: Mass $m = 4 \, kg$,Force $F = 16 \, N$,Initial velocity $u = 0$,Time $t = 10 \, s$.Step $1$: Calculate acceleration $a$ using Newton's second law,$F = ma$.$a = \frac{F}{m} = \frac{16 \, N}{4 \, kg} = 4 \, m/s^2$.Step $2$: Calculate final velocity $v$ using the equation of motion $v = u + at$.$v = 0 + (4 \, m/s^2 	imes 10 \, s) = 40 \, m/s$.Step $3$: Calculate kinetic energy $KE$ using the formula $KE = \frac{1}{2}mv^2$.$KE = \frac{1}{2} 	imes 4 \, kg 	imes (40 \, m/s)^2 = 2 	imes 1600 = 3200 \, J$.

$A$ body of mass $4 \, kg$ initially at rest is subjected to a force of $16 \, N$. What is the kinetic energy acquired by the body at the end of $10 \, s$ (in $, J$)?
