**Problem:**A mouse of mass 30.0 grams falls 130 meters down a vertical mine shaft and lands at the bottom with a speed of 8.1 meters per second. During its fall, how much work (in Joules) is done on the mouse by air resistance?**Solution:**Given:- Mass of mouse (m) = 30.0 g = 0.030 kg (conversion from grams to kilograms)- Distance fallen (h) = 130 m- Final speed (v) = 8.1 m/s- Work done by air resistance (W) = ?To solve this, you'd use the work-energy principle, considering both gravitational potential energy and kinetic energy.**Answer:**-248.21 JThe negative sign indicates that the work done by air resistance is opposite to the direction of motion, implying energy was lost to air resistance during the fall.
