A 99 g ball is tied to the end of a 49 cm long string and swung clockwise in a vertical circle. The center of the circle is 175 cm above the floor. What is the minimum speed necessary to make it over the top without the string going slack?
The ball is being swung at this minimum speed, but then the string is released at the instant the ball is at the top of the loop. How far to the right does the ball hit the ground?

2. A ball tied to the end of a string 65 cm in length swings in a vertical circle under the influence of gravity. When the string makes an angle of thetha=25 degrees with the vertical, the ball has a speed of 2.0 m/s. a. Find the magnitude and the direction of the total acceleration when thetha=25 degrees.

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?

A 100g ball is tied to a string so that the center of mass hangs 50 cm below the point where the string is tied to a support rod. The ball is pulled aside to a 60° angle with vertical and released. As the string approaches vertical, it encounters a peg D cm below the support rod. The string then bends around the peg. What is the smallest value of D for which the ball will move in a circle...

9 A small 2kg ball is tied to a massless string 2m long to form a pendulum that is then set swinging by releasing the ball from rest when the string makes an angle 30° with vertical. Neglecting all kinds of friction, what is the ball's speed when the string is vertical? What is the ball's speed when the string makes an angle 10° with vertical? 10. A 1000 kg...

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...

Suppose you swing a ball of mass m in a vertical circle on a string of length L. As you probably know from experience, there is a minimum angular velocity ωmin you must maintain if you want the ball to complete the full circle without the string going slack at the top. Find an expression for ωmin in terms of g and L . Evaluate ωmin in rpm for a 65 g ball tied to a 1.4-m-long string.

A small ball of mass m is tied to a string and set rotating with negligible friction in a vertical circle of radius R with earth's gravity g acting. (a) What is the speed of the ball at the top of the circle so that the tension in the string vanishes there? (b) Given this, what is the speed of the ball at the bottom of the circle, and (c) what is the tension in the string at the bottom...

A mass is attached to one end of a massless string, the other
end of which is attached to a fixed support. The mass swings around
in a vertical circle as shown in Fig. 5.36. Assuming that the mass
has the minimum speed necessary at the top of the circle to keep
the string from going slack, at what location should you cut the
string so that the resulting projectile motion of the mass has its
maximum height located directly...

1. You can swing a ball on a string in a vertical circle if you swing it fast enough. But if you swing too slowly, the string goes slack as the ball nears the top. Explain why there's a minimum speed to keep the ball moving in a circle.
