A solid cylindrical pulley has a radius of 8 cm and a mass of 220 grams. A string of negligible mass is wrapped around the circumference of the pulley wheel and a 50-gram mass is attached to the free end of the string and allowed to hang freely. The system is released from rest and the box descends 1.4 meters.
(a) What is the linear speed of the box after this descent?
(b) What is the tension In the vertical length of the string at that moment?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
