You stand on your skateboard and exert a 50-N push on the wall next to you. If your mass is 60 kg you'll momentarily accelerate from the wall at about A)0.08 m/s². B)0.8 m/s². C)8.0 m/s². D)none of the above

According to Newton's third law, the force you exert on the wall will be exerted back on you. Using Newton's second law, $F = ma$, where $F = 50\,N$ and $m = 60\,kg$, we can solve for acceleration $a$. Rearranging the formula gives us $a = \frac{F}{m} = \frac{50\,N}{60\,kg} = 0.83\,m/s^2$, which rounds to $0.8\,m/s^2$, making option B the correct choice.
