A light rigid rod is 76.7 cm long. Its top end is pivoted on a low-friction horizontal axle. The rod hangs straight down at rest with a small massive ball attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swings around in a full circle. What minimum speed at the bottom is required to make the ball go over the top of the circle

8.4 A light, rigid rod is 62.8 cm long. Its top end is pivoted on a frictionless horizontal axle. The rod hangs straight down at rest with a small, massive ball attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swings around in a full circle. What minimum speed at the bottom is required to make the ball go over the top of the circle? ________________m/s

A 79g , 40-cm-long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 15g ball of clay traveling horizontally at 2.0m/s hits and sticks to the very bottom tip of the rod. To what maximum angle, measured from vertical, does the rod (with the attached ball of clay) rotate?

A massless rigid rod whose length L = 21.0 cm has a ball of mass
m = 0.079 kg attached to one end (see Figure). The other end is
pivoted in such a way that the ball will move in a vertical circle.
The system is launched from the horizontal position A with an
initial downward speed v0. The ball just reaches point D
and then stops. Calculate v0.

A long, uniform rod of mass 20.00 kg is pivoted at its top end. It is lifted a small angle and let go. When it reaches the very bottom of its swing, it is moving with angular speed ?o , and it has collision with a block of mass 3.000 kg that was originally at rest on a frictionless surface. After the collision the rod is seen to continue spinning in the same direction at 17.66 rad/s. As a result...

A slender, uniform metal rod of mass M and length l is pivoted
without friction about an axis through its midpoint and
perpendicular to the rod. A horizontal spring, assumed massless and
with force constant k, is attached to the lower end of the rod,
with the other end of the spring attached to a rigid support.

Review A 76 g , 40-cm-long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 11 g ball of clay traveling horizontally at 2.2 m/s hits and sticks to the very bottom tip of the rod. A) To what maximum angle, measured from vertical, does the rod (with the attached ball of clay) rotate? Express your answer to two significant figures and include the appropriate units.
