148956 A ball of mass $2 \mathrm{~kg}$ is moving in $x y$ plane with a potential energy given as $U=(12 x+16 y) J, x$ and $y$ being in meter. Assume the initial position of the ball at $t=0$ is at origin $(0,0)$ and it is moving with a velocity of $(15 \hat{\mathbf{i}}+20 \hat{\mathbf{j}}) \mathrm{m} / \mathrm{s}$. Then identify the correct statement.
