A 0.70 kg ball on the end of a 1.10 meter long string is swung above the head of a physics student at a constant rate (assume that the string is horizontal during this motion). If the string can experience a maximum tension of 10.0 N before snapping, what is the fastest the ball can be swung?

7. A 2 kg tether ball hangs on a 1.2 meter long string. The string can sustain a maximum tension of 30 N before it breaks. To test this, we spin the ball faster and faster until we reach its maximum velocity. (a) Draw a force triangle for this extreme case, inctuding the string tension and the gravitaticnal force. On the diagram, show the strengdh of all three sides and the valucs of the angles b) How fast is the...

A 5.0 kg ball is swung in a vertical circle with a radius of 75 cm. At the lowest point in its motion the ball is 40 cm above the ground. When the ball is at the highest point the tension in the string is 75 N when suddenly the string breaks. How far away horizontally does the ball hit the ground (measured from where it was when the string broke)? Include a diagram showing the circular motion the ball...

A 0.3 kg ball, at the end of a 0.75 m string is swung in a circle at a constant velocity of 4 m/sec. The centripetal force of the ball is: _________ , and the angular momentum of the ball is: _________. I know that the answer is: 6.4 N and 0.9 kgm2, but I have no idea how to solve the answer. Please explain and show all of the steps to get the answer.

You are given a (massless) piece of string that is L=1.10 m long, and tied to the end of it is an object of mass m=5.40 kg. Like any string, it will rip if there is too much tension in it, and for this string that maximal amount of tension is T=104 N. a) If you held this string at one end and twirled it in a circle above your head, so that the object moves in a plane parallel...

A child is swinging a 380-g ball at the end of a 69.0-cm-long string in a vertical circle. The string can withstand a tension of 16.0 N before breaking. (a) What is the tension in the string when the ball is at the top of the circle if its speed at that point is 3.90 m/s? (b) What is the maximum speed the ball can have at the bottom of the circle if the string does not break?
