    Forced Frequency Homework: Which of These Acts as a Force?

    Homework Statement Which of the following is a forced frequency acting on the oscillations? I. A pendulum skims the surface of a pool of water at the lowest point of motion. II. To keep a bell ringing, a bell ringer pulls on a bell rope. III. A singer shatters a glass. Homework EquationsThe...

    What is the Maximum Radius for a Bucket of Water in Circular Motion?

    So g = -9.81. Is Fc equal to Fg or something like that then ?

    What is the Maximum Radius for a Bucket of Water in Circular Motion?

    Well I sort of figured that. I'm not trying to get out of doing the work, I'm just not sure what formula I should use or how I should go about the question.

    What is the Maximum Radius for a Bucket of Water in Circular Motion?

    Homework Statement A 3.75 kg bucket pile of water is swung in a vertical circle. If the speed of the bucket at the top of the loop is 6.20 m/s, then the radius of the largest circle through which this pail could move without the water leaving the bottom of the pail would be what? m = 3.75 kg...

    Finding Initial Speed given Kinetic Friction, Mass, and more

    Yes! I think we may have referred to this in different terms though? So for the vertical direction: Fnet = FNormal + Fg. This cancels out giving zero. For the Horizontal Direction we have Fnet = ma Ffk = μkFN

    Finding Initial Speed given Kinetic Friction, Mass, and more

    Can you help me with this? I do not know what "force balance" is.

    Finding Initial Speed given Kinetic Friction, Mass, and more

    Forces acting on the stone in the vertical direction are: Normal Force and the Force of Gravity. Forces acting on the stone in the horizontal direction are Applied Force and the Kinetic Friction. The net force in the horizontal direction should be equal to the Force Applied plus Force of Kinetic...

    Finding Initial Speed given Kinetic Friction, Mass, and more

    Ohhhh, well the acceleration will be in the horizontal or x direction as the rock isn't flying up in the air. So the sum of the forces in the vertical direction would be 0 N. I'm not actually sure how to determine the sum of forces in the horizontal direction, given the values. I'm sorry :(...

    Finding Initial Speed given Kinetic Friction, Mass, and more

    Would that mean: FN = ma Fg = mg Ffk = μkFN

    Finding Initial Speed given Kinetic Friction, Mass, and more

    I have not written out the force balances. If I may ask, what are those? I may have learned them but referred to under different terms.

    Finding Initial Speed given Kinetic Friction, Mass, and more

    Hi, I'm new here and I'm having trouble with a question. 1. Homework Statement A 20.0-kg curling stone is released at the hog line and moves 28.35 m [W] to sit on the button and score a point. If the coefficient of kinetic friction between the stone and the ice is 0.00200, what was the...
