A woman is pulling a wheeled suitcase (mass = 20.0 kg) by a strap at an angle of θ above the horizontal. She pulls on the strap with a force of 22.0 N, and the friction force between the wheels and the floor is 15.0 N. Assume constant horizontal velocity (no acceleration in the horizontal direction). Do not forget significant figures!!!! (30 points) Do not include units in your answer- e.g, 8.68 What angle does the strap make with the horizontal? _______ What is the magnitude of the normal force that the ground exerts on the suitcase? Do not forget significant figures!!!! Do not include units in your answer- e.g, 8.68 _______ Bonus Question: What is the coefficient of friction? (+10 points) _______

The distance from the university to home is 10.75 mi and it usually takes 24 min to drive this distance. Calculate the average speed in meters per second (m/s). (Note: Average speed is distance traveled divided by time of travel.) Do not forget significant figures!!!! (20 points) Please put only the numerical answer in the box WITHOUT UNITS (e.g. 7.0) Hint: 1 mile = 1.6 km _______
