A ball of mass m is suspended from a string, and after being given a push,moves along a horizontal circular path like the one shown in the diagram.The length of the string is L and the angle the string makes with the vertical axis is a constant θ. As you watch the ball travel around it’s circular path you notice that the ball is traveling with an unknown constant speed. The only forces acting on the ball are the forces of the string and the Earth.
A. Calculate the parallel component of the rate of change of momentum for the ball.
B. Determine the magnitude of the tension in the string. Your answer should not depend on the unknown velocity of the ball.
C. Calculate the perpendicular component of the rate of change of momentum for the ball. Your answer should not depend on the unknown velocity of the ball.
D. Calculate the speed of the ball in terms of the known quantities given in the problem statement and universal constants.

Consider a ball of mass 0.110 kg being spun in a horizontal circle of radius r-0.50 m, as shown to the right. When the ball reaches an angular velocity (o) of 2.00 rad/s, it is given a constant angular acceleration of a- 2.00 rads. You can assume that the radius of the circular path followed by the ball remains constant during this acceleration. After precisely 3.00 seconds of this angular acceleration, the ball breaks off the string (a) In what...

An object of mass m moves at a constant speed v in a circular path of radius r.
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...
