1. A passenger sits in an airplane with a seatbelt on. Air resistance ls large. The plane Initially files at a constant speed and then the engines malfunction and turn off. a) For the situation before the engines fail, draw the F30 of the passenger and determine what you can about the acceleration of the passengers in the frame of reference of the plane and in the frame of the ground outside the plane. b) For the situation shortly after the engines fail, draw the FBD of the passenger and determine what you can about the acceleration of the passenger in the frame of reference of the plane and in the frame of reference of the ground outside the plane. o) Is there an apparent force that is not real that seems to act in one of the frames of reference in either part a or b above? Explain your thinking. 2. No toy wagons are tied together by ropes. as shown below. Rope B Is being pulled with a force of 25H. The mass of wagon 1 is 4.0 kg, and the mass of wagon 2 is 5.0 kg. Assume the force of friction on the wagon is negligible. a) What is the acceleration of both the wagons? b b) Calculate the tension in each rope. c) Now suppose instead that there is friction between the wagons and the ground. It us = 0.30 and uK = 0.15, will the sled move? What are the forces of friction? What is the acceleration? 3. Janine ls pulllng a sled up a straight slope that makes an angle of 20 with the horizontal. The sled has a mass of 10.0 kg. Suddenly, the rope snaps and Janine Is no longer able to pull the sled at all? a) If the force of friction is negligible, what will be the acceleration of the sled? b) if us = 0.25 and u\": 0.05, will the sled move? What is the force of friction? What is the acceleration
