Physics - W.E.P. Question with Solution | TestHub

The potential energy of a particle of mass$\mathrm{5 }\mathrm{k}\mathrm{g}$moving in the$\mathrm{x}-\mathrm{y}$plane is given by$\mathrm{U}=\left(-7\mathrm{x}+24\mathrm{y}\right)\mathrm{ }\mathrm{J}$, where$\mathrm{x}$and$\mathrm{y}$are in meters. If$\mathrm{t}=0$, the particle starts from rest from the origin, then speed of the particle at$\mathrm{t}=\mathrm{2 }\mathrm{s}$is
