QUESTION
7a You are on a fishing trip, not catching anything, and bored - time for physics! You drop your $50 \mathrm{~g}$ weight to the bottom of the lake under constant tension from the string of magnitude $0.1 \mathrm{~N}$. The damping constant for your falling weight is $2.5 \mathrm{~kg} / \mathrm{s}$. What is the terminal velocity of the weight? Give your answer in $\mathrm{m} / \mathrm{s}$ and assume the positive direction is upwards. $-0.639$ (X) Incorrect 7b If it takes $500 \mathrm{~s}$ for the weight to reach the bottom of the lake, how deep is the lake? Give your answer in $\mathrm{m}$. $-319.85$ Incorrect
