Three objects are set in motion, a $4\mathrm{.}0kg$ object at $2\mathrm{.}4\frac{m}{s},$ a $3\mathrm{.}2kg$ object at $3\mathrm{.}2\frac{m}{s},$ and a $2\mathrm{.}4kg$ object at $4\mathrm{.}0\frac{m}{s}.$ Which object has the most kinetic energy? the $4\mathrm{.}0kg$ object at $2\mathrm{.}4\frac{m}{s}$ the $3\mathrm{.}2kg$ object at $3\mathrm{.}2\frac{m}{s}$ the $2\mathrm{.}4kg$ object at $4\mathrm{.}0\frac{m}{s}$ Since the mass and velocity add together to $6\mathrm{.}4$ in each case, the kinetic energy for each object is the same.
