. A simple pendulum consists of a 2.0 kg brass bob on a string about 0.5 m long. It has a period of about 1.42 sec. The pendulum would have a period of about 5 seconds if the A. string were replaced by one 25 m long. B. string were replaced by one 6.2 m long. C. bob were replaced by a 0.6 kg brass sphere. D. bob were replaced by a 7.0 kg brass sphere. E. bob was released from a 0.5 m height.

A pendulum consists of a 2.2-kg bob attached to a light 2.0-m-long string. While hanging at rest with the string vertical, the bob is struck a sharp horizontal blow, giving it a horizontal velocity of 4.5 m/s. At the instant the string makes an angle of 27 degree with the vertical, calculate the following: (a) the speed m/s (b) the gravitational potential energy (relative to its value is at the lowest point) J (c) the tension in the string?

A pendulum consists of a 2.2 kg bob attached to a 2.8 meter long string. The bob has a velocity of 4.7 m/s as it passes the bottom. Considering the point where the string makes a 29° angle with the vertical, determine the tension in the string. Could you please double check my solution? I think the solution is F= mg + mgh F = (2.2) (9.8) + (2.2) (9.8) (0.36) F 29.32 or F = mg +0.5 m (V^2)...

A grandfather clock has a pendulum that consists of a thin brass
disk of radius 37 cm and mass 1.6 kg that is attached to a long,
thin rod of negligible mass. The pendulum swings freely about an
axis perpendicular to the rod and through the end of the rod
opposite the disk. The pendulum should be designed so that its
period is 2 s for small oscillations when the gravitational
acceleration is 9.8 m/s2.
