You have just landed on Planet X. You release a $100 \mathrm{~g}$ ball from rest from a height of $10.0 \mathrm{~m}$ and measure that it takes $3.40 \mathrm{~s}$ to reach the ground. Ignore any force on the ball from the atmosphere of the planet. How much does the $100 \mathrm{~g}$ ball weigh on the surface of Planet X?
