Circular Motion: Deriving r for Two Objects on a String
Homework Statement A small object of mass m1 moves in a circular path of radius r on a frictionless horizontal tabletop. It is attached to a string that passes through a frictionless hole in the center of the table. A second object with a mass of m2 is attached to the other end of the...- makerfeldt

What Forces Determine the Sliding of a Block on a Wedge?
Homework Statement A block of mass 0.80 kg rests on the inclined surface of a wedge of mass 2.0 kg. The wedge is acted on by a horizontal force F and slides on a frictionless surface. If the coefficient of static friction between the wedge and the block is µs = 0.40, and the angle of the...- makerfeldt

How to Calculate Forces and Acceleration of Boxes on a Frictionless Shelf?
Homework Statement A box of mass m2 = 3.7 kg rests on a frictionless horizontal shelf and is attached by strings to boxes of masses m1 = 1.2 kg and m3 = 2.1 kg as shown below. Both pulleys are frictionless and massless. The system is released from rest. After it is released, find the...- makerfeldt

How Is the Smallest Force to Move a Box Up a Ramp Calculated?
The initial angle given for the rope (42) was the angle it makes with the horizontal, but that is not the horizontal I used. I rotated the axis 14.9 so that I could make the ramp's surface the new horizontal. As a result, I reasoned that the new angle the rope would make with the horizontal...- makerfeldt

How Is the Smallest Force to Move a Box Up a Ramp Calculated?
Homework Statement A 19.0 kg box sits on a frictionless ramp with a 14.9° slope. The movers pull up a rope attached to the box to move it up. If the rope makes an incline with the ramp that is 42.0° to the horizontal, what is the smallest force F the mover must use to move the box up the...- makerfeldt
