A 300g ball on a 65-cm-long string is swung in a vertical circle about a point 200 cm above the floor. The string suddenly breaks when it is parallel to the ground and the ball is moving upward. The ball reaches a height of 600 cm above the floor.

Ā 

What was the tension in the string at the instant before it broke?

A 60 g ball is tied to the end of a 50- cm-long stringandswung in a vertical circle. The center of the circle, as showninthe figure , is 150 cm above the floor. The ball is swung attheminimum speed necessary to make it over the top without thestringgoing slack.
If the string is released at the instanttheball is at the top of the loop, how far to the right does theballhit the ground?

A ball of mass m=.275 kg swings in a vertical circular path on astring L= .850m long. A) what are the forces acting on the ball atany point on the path?
b) draw the force diagrams for the ball when it is at the bottom ofthe circle and when it is at the top. c) if its speed is 5.2m/s atthe top of the circle what is the tension in the string there? d)if the string breaks when its tension exceeds 22.5N what is themaximum speed the ball can have at the bottom before that happen.

A 0. 10-kilogram solid rubber ball is attached to the end of an0.80-meter length of light thread. The ball is swung in a verticalcircle, as shown in the diagram above. Point P, the lowest point ofthe circle, is 0.20 meter above the floor. The speed of the ball atthe top of the circle is 6.0 meters per second, and the totalenergy of the ball is kept constant.
a. Determine the total energy of the ball, using the floor as thezero point for gravitational potential energy.
b. Determine the speed of the ball at point P, the lowest point ofthe circle.
c. Determine the tension in the thread at
i. the top of the circle;
ii. the bottom of the circle.
The ball only reaches the top of the circle once before the threadbreaks when the ball is at the lowest point of the circle.
d. Determine the horizontal distance that the ball travels beforehitting the floor.
