Kinetic energy:

$\overline{){\mathbf{K}}{\mathbf{E}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{2}}{\mathbf{m}}{{\mathbf{v}}}^{{\mathbf{2}}}}$

Momentum:

$\overline{){\mathbf{p}}{\mathbf{=}}{\mathbf{m}}{\mathbf{v}}}$

p^{2} = m^{2}v^{2}

Two toy cars with masses as given are ready to race. Both cars begin from rest. The same force is applied to each car for 10 s.

For each question, state whether the correct answer is car A, car B, or whether the two cars have equal values for the parameter in question.

Car A = 1.00 kg

Car B = 1.62 kg

After 10 s which car has a larger kinetic energy? Why? Explain in detail

Car A, Car B, or Neither?
