(B) Given: Force $F = 20 \,N$,time $t = 10 \,s$,mass $m = 5 \,kg$,and initial velocity $u = 0 \,m/s$.First,calculate the acceleration $a$ using Newton's second law: $a = F/m = 20/5 = 4 \,m/s^2$.Next,calculate the final velocity $v$ after $10 \,s$ using the equation $v = u + at$: $v = 0 + (4 	imes 10) = 40 \,m/s$.Finally,calculate the kinetic energy $KE$ using the formula $KE = 1/2 	imes m 	imes v^2$: $KE = 1/2 	imes 5 	imes (40)^2 = 1/2 	imes 5 	imes 1600 = 4000 \,J$.

$A$ block of mass $5 \,kg$ is lying on a frictionless table. $A$ force of $20 \,N$ is applied on it for $10 \,s$. Calculate its kinetic energy. (in $J$)
