Q1 : A mass ( m1 ) of 1.20 kg is situated at the bottom of an incline that is 30o to the horizontal. At the top of the incline, there’s a 0.500 kg disk that is kept fixed by a frictionless axle. A cord is placed over the disk and used to lift aContinue reading “AP PHYSICS: Final Speed of a Block / Incline System”

AP PHYSICS: Pulleys, Torque, Tension, and the Moment of Inertia
Two spherical bearings of mass ( m1 ) and ( m2 ) are attached by belt to a pulley that is situated between them. An electric motor is also attached to the pulley, and it is positioned between these masses. When the motor is turned on, the pulley provides 15.0 N of tension on theContinue reading “AP PHYSICS: Pulleys, Torque, Tension, and the Moment of Inertia”
FORCE AND ACCELERATION: Pulleys, Tension, Friction, and Free-Body Diagrams
Q: Three objects are connected by ropes that pass over massless and frictionless pulleys. As the objects move, the table exerts a force of friction on the middle object. The coefficient of kinetic friction is 0.100. What is the acceleration of the three objects within the system? What is the magnitude of the tension inContinue reading “FORCE AND ACCELERATION: Pulleys, Tension, Friction, and Free-Body Diagrams”
