In a horizontal uniform circular motion, is the centripetal force acting on the stopper provided by the tension in the string, always equal to the weight of the hanging mass?
A 5.0 kg-mass rotates horizontally at a rate of 1 revolution per second. If the radius of the circular path it describes is 2.0 m find the magnitude of its centripetal acceleration.
A car, with mass m, is racing around a circular track with some velocity v. If the car suddenly had its mass tripled and velocity doubled, what would happen to the centripetal acceleration needed for the car to conitnue circular motion?
