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.

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.

You swing a rock tied to a string in a vertical circle. (A) Construct a consistent force diagram for the rock as it passes the low point in its swing. Use two vectors (mg and Tbottom). (B) Determine the force that the string exerts on the rock. Express your answer in terms of vt (speed of the rock in the high point in its swing), R ( length of the string), m ( mass of the rock), and constant g.

A spherical mass on the end of a string is spinning in a vertical circle about point P. Which of the forces acting on the mass contribute to the "centripetal force" when the mass is in position A? Select all that apply. The tension in the string. The force of gravity (weight). The force of drag (air resistance). Which of the forces acting on the mass contribute to the "centripetal force" when the mass is in position B, directly to...

A stone is tied to a string (length L = 1.10 m) and whirled in a circle at the same constant speed in two different ways. First, the circle is horizontal, and the string is nearly parallel to the ground. Next, the circle is vertical. In the vertical case, the maximum tension in the string is 15.0% larger than the tension that exists when the circle is horizontal. step 6: Draw the free-body diagram for the forces acting on the...
