Q1. It's a snowy day and you're pulling a friend along the level road on a sled. You've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. You've been walking at a steady, and rope pulls up on the sled at a 21 angle. You estimate that the mass of the sled, with your friend on it, is 64 and that you're pulling with a force of 84.0.

Q2. A skydiver of mass 75.50 kg jumps from a slow-moving aircraft and reaches a terminal speed of 49.90 m/s. What is her acceleration if her speed is 30.0 m/s?
