A woman at an airport is towing her 22.0 kg suitcase at constant speed by pulling on a strap at an angle ? above the horizontal (see figure). She pulls on the strap with a 38.0 N force, and the friction force on the suitcase is 20.0 N. What angle does the strap make with the horizontal (in degrees)? What is the magnitude of the normal force that the ground exerts on the suitcase (in N)? What If? If the woman still pulls on the strap with a 38.0 N force but wishes to accelerate the suitcase at a rate of 0.500 m/s2, at what angle (in degrees) must she pull on the strap? Assume that the rolling friction is independent of the angle of the strap. What is the maximum acceleration of the suitcase if the woman can exert a maximum force of 38.0 N? (Enter the magnitude in m/s2.)

Question

A woman at an airport is towing her 22.0 kg suitcase at constant speed by pulling on a strap at an angle ? above the horizontal (see figure). She pulls on the strap with a 38.0 N force, and the friction force on the suitcase is 20.0 N.

What angle does the strap make with the horizontal (in degrees)?

What is the magnitude of the normal force that the ground exerts on the suitcase (in N)?

What If? If the woman still pulls on the strap with a 38.0 N force but wishes to accelerate the suitcase at a rate of 0.500 m/s2, at what angle (in degrees) must she pull on the strap? Assume that the rolling friction is independent of the angle of the strap.

What is the maximum acceleration of the suitcase if the woman can exert a maximum force of 38.0 N? (Enter the magnitude in m/s2.)
