An object is moving at a constant speed around a circle. In which of these cases does the magnitude of the centripetal acceleration of the object increase the most? The radius of the circle doubles The object's speed doubles The object's speed is halved The radius of the circle is halved

A small object of mass m moves in a horizontal circle of radius r on a rough table. It is attached to a horizontal string fixed at the center of the circle. The speed of the object is initially v0. After completing one full trip around the circle, the speed of the object is 0.5v0. (a) Find the energy dissipated by friction during that one revolution in terms of m, v0, and r. (Use any variable or symbol stated above...
A particle object undergoes uniform circular motion at a speed v around a circle of radius r. Given v and r, the magnitude of centripetal acceleration is a0. Assume when either v or r are changed, the particle remains in uniform circular motion. 1. Suppose the radius of the circle is cut in half. What happens to the magnitude of the centripetal acceleration? choices: the acceleration doubles, acceleration increases by square root of 2, acceleration remains the same, acceleration decreases...
A particle of mass m moves in a circle of radius R at a constant speed v, as shown below. The motion begins at point Q at time t = 0. Determine the angular momentum of the particle about the axis perpendicular to the page through point P as a function of time.

A mass m = 2.77 kg is attached to a spring of force constant k = 44.9 N/m and set into oscillation on a horizontal frictionless surface by stretching it an amount A = 0.11 m from its equilibrium position and then releasing it. The figure below shows the oscillating mass and the particle on the associated reference circle at some time after its release. The reference circle has a radius A, and the particle traveling on the reference circle...
An object of mass m moves at a constant speed v in a circular path of radius r. The force required to produce the centripetal component of acceleration is called the centripetal force and is given by F=mv2/r. Newton's Law of Universal Gravitation is given by F=GMm/d2, where d is the distance between the centers of the two bodies of masses M and m, and G is a gravitational constant. The speed required for circular motion is v= √(GM/r). Use the...
Calculate the net acceleration of an object moving in a circle of radius 20 m if the object is moving at a constant speed of 15 m/s. Also calculate the net acceleration of the object when it speeds up from 15 m/s to 60 m/s in 5 seconds at the instant when its moving at 15 m/s and when it is moving at 60 m/s.
