MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A woman at an airport is towing her 23.5 kg suitcase at constant speed by pulling on a strap at an angle 0 above the horizontal (see figure). She pulls on the strap with a 37.2 N force, and the friction force on the suitcase is 20.0 N. (a) Draw a free-body diagram of the suitcase. Choose File No file chosen This answer has not been graded yet. (b) What angle does the strap make with the horizontal (in degrees)? (c) What is the magnitude of the normal force that the ground exerts on the suitcase (in N)? N (d) What If? If the woman still pulls on the strap with a 37.2 N force but wishes to accelerate the suitcase at a rate of 0.500 m/s, at what angle (in degrees) must she pull on the strap? Assume that the rolling friction is independent of the angle of the strap. (e) What is the maximum acceleration of the suitcase if the woman can exert a maximum force of 37.2 N?

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A cord passing over a pulley connects two masses, as shown, where m, = 4.00 kg and my = 7.00 kg. The system accelerates with a magnitude of 1.10 m/s. The coefficient of kinetic friction between the masses and the incline is the same for both masses. Assume the pulley is frictionless, and the cord is massless.
