Q1- A woman at an airport is towing her 15.0 kg suitcase at constant speed by pulling on a strap at an angle above the horizontal. She pulls on the strap with a 40 N force, and the friction force on the suitcase is 20.0 N.
(a) Draw a free-body diagram of the suitcase.
(b) What angle does the strap make with the horizontal?
(c) What normal force does the ground exert on the suitcase?
Q2- A 9.00 kg hanging weight is connected by a string over a pulley to a 5.00 kg block that is sliding on a flat table. The string is light and does not stretch; the pulley is light and turns without friction. The coefficient of kinetic friction between the sliding block and the table is 0.190. Find the tension in the string.
