WebbForces of Friction Problems and Solutions 2. A woman at an airport is towing her 20.0-kg suitcase at constant speed by pulling on a strap at an angle θ above the horizontal (Fig. 1). She pulls on the strap with a 35.0-N force, and the friction force on the suitcase is 20.0 N. Draw a free-body diagram of the suitcase. WebbThree Physics home work problems. 1).

Numerical Problems Based on Class 11 Physics Friction

WebbSolve the following problems. A 1130-kg car is held in place by a light cable on a very smooth (frictionless) ramp, as shown in figure. The cable makes an angle of 43° above the surface of the ramp, and the ramp itself rises at 39° above the horizontal. (a) Draw a free-body diagram for the car. (b) Find the tension in the cable. WebbStatic friction is the force which opposes the initiation of motion of an object on the surface. When the object is at rest on the surface, only two forces act on it. They are the downward gravitational force and upward normal force. The resultant of these two forces on the object is zero. As a result the object is at rest as shown in Figure 3.23. WebbNewton's 2nd law, friction Problem: A box of mass m slides across a horizontal table with coefficient of friction μ. The box is connected by a rope which passes over a frictionless pulley to a body of mass M hanging along side the table. Find the acceleration of the system and the tension in the rope.
