a tetherball on a 1.55m rope is struck so that it goes into circular motion in a horizontal plane, with the rope making a 12 degree angle to the horizontal. what is the balls speed

Pablo ties a small stone to the end of a rope and is spun in a horizontal circle. If the mass of the stone is 0.40 kg and that of the rope is 0.75 m. What is the largest speed that the stone can have if the rope will break when the tension is 260 N?

A ball traveling from point A to point E on the surface of the Earth follows the trajectory shown in the figure. B с it is straight down What is the direction of the acceleration at point B? it is down and to the left The acceleration of the ball is zero D it is straight up it is up and to the right E

A ball is on the end of a string. The ball is being swung in a vertical circle at a constant speed.The length of the string is 1.30 m. The mass of the ball is 2.10 kg. The maximum tension the string can withstand before breaking is 54.0 N.What is the maximum speed of the ball without the string breaking when the ball is at the top of the circle (Point A in the figure)?

Experimental Ezra ties a 59.4 g tennis ball to a string and swings it in a vertical circle. Ezra swings the ball so that it always has constant speed of v = 4.82 m/s. The radius of the swing is r = 0.787 m and Ezra's hand is H = 1.40 m above the ground as shown. y H
