A body of mass $6 \mathrm{~kg}$ is acted upon by a force which causes a displacement in it given by $x=\frac{t^{2}}{4} \mathrm{~m}$ where $t$ is the time in second. The work done by the force in 2 second is (a) $12 \mathrm{~J}$ (b) $9 \mathrm{~J}$ (c) $6 \mathrm{~J}$ (d) $3 \mathrm{~J}$
A body of mass $6 \mathrm{~kg}$ is under a force, which causes a displacement in it given by $\mathrm{S}=\left[\left(2 \mathrm{t}^{3}\right) / 3\right](\mathrm{in} \mathrm{m}) .$ Find the work done by the force in first one seconds. (A) $2 \mathrm{~J}$ (B) $3.8 \mathrm{~J}$ (C) $5.2 \mathrm{~J}$ (D) $24 \mathrm{~J}$
A body of mass $3 \mathrm{~kg}$ is under a force which causes a displacement in it, given by $s=t^{2} / 3$ (in m). Find the work done by the force in $2 \mathrm{~s}$ (a) $2 \mathrm{~J}$ (b) $3.8 \mathrm{~J}$ (c) $5.2 \mathrm{~J}$ (d) $2.6 \mathrm{~J}$
