An athlete swings a ball, connected to the end of a chain, in a horizontal circle. The athlete is able to rotate the ball at the rate of 8rev/s when the length of the chain is 0.600m. when he increases the length to 0.900 m, he is able to rotate the ball 6.00 rev/s.

(a) which rate of rotation gives the greater speed for the ball?

(b) what is the centripetal acceleration of the ball at 8.00 rev/s?

(c) what is the centripetal acceleration of the ball at 6.00 rev/s?

A ball is attached to a string and swung in a horizontal circle at a constant speed. Assume air resistance is negligible. If the string tripled in length but the speed of the ball remained the same, show mathematically how the inward force on the ball would change.

A ball is tied to a string and whirled in a horizontal circle at a constant 4 revolutions per second. Categorize the following according to whether they are constant and zero in value, constant and non-zero in value, or non-constant in value: linear speed (scalar) linear velocity (vector) radial (centripetal) acceleration (scalar) radial (centripetal) acceleration (vector) angular speed (scalar) angular velocity (vector) angular acceleration (scalar) angular acceleration (vector)

A rigid massless rod is rotated about one end in a horizontal circle. There is a load of mass m attached to the center of the rod, and one of mass M attached to the outer end of the rod. The inner section of the rod sustains a tension that is three times as great as the tension that the outer section sustains. The mass ration of m/M is? Answer is 1 WHY?

A block with mass M is connected to one end of a horizontal spring of constant k, the other end of which is attached to the wall. The block moves with a simple harmonic motion on a frictionless surface. The amplitude of the harmonic motion is A1. When the block passes through the equilibrium position, a piece of plasticine, of mass m, is dropped vertically on the block and remains glued to it. Calculate the energy of the system in...

Al is twirling a ball horizontally around his head. The ball moves in a circle because there is a force on the ball pulling it outward. tension in the string continuously pulls the ball inward. once the ball starts moving, circular motion is its natural tendency. the ball’s force is perpendicular to its acceleration.
