A simple pendulum is shown in several states. In case A the mass is traveling back down to the bottom and is in between the bottom and its max height. In case B the mass is at its max height and has a speed of zero. In case C the ball is at its lowest position.Which of the following statements about the magnitude of the mass's angular acceleration is true?a) It is maximum in case A.b) It is maximum in case B.c) It cannot be determined d) It is zero in all cases. e) It is maximum in case C.f) It is equal in all cases, but is non-zero.

In a science museum, a 110kg brass pendulum bob swings at the end of a 13.2m -long wire. The pendulum is started at exactly 8:00 a.m. every morning by pulling it 1.7m to the side and releasing it. Because of its compact shape and smooth surface, the pendulum's damping constant is only 0.010 rm kg/s. At exactly 12:00 noon, how many oscillations will the pendulum have completed? And what is its amplitude?

Rank each pendulum on the basis of the maximum kinetic energy it attains after release. Rank from largest to smallest. To rank items as equivalent, overlap them.

A pendulum is made by tying a 420g ball to a 51 cm long string. The pendulum is pulled 25 degrees to one side, then released.(a) what is the ball's speed at the lowest point of its trajectory?(b) To what angle does the pendulum swing on the other side?

A simple pendulum consisting of a bob of mass m attached to a string of length L wings with a period T.A. If the mass of the bob is reduced by half, what will the new period of oscillation be?a. T/2b. 2Tc. T/ √2d. TB. The pendulum is now swinging on Pluto. Express the new period of oscillation in terms of T (the period of the pendulum on Earth), knowing that the gravity on Pluto is 1/16 that of Earth.

After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 53.0 cm. The pendulum completes 104 full swing cycles in a time of 127 seconds; What is the magnitude of the gravitational acceleration on this planet? Express in m/s2

Rank each pendulum on the basis of its maximum speed.Rank from largest to smallest.

Which of the following is a true statement about the acceleration a→of the pendulum bob?A. a→ is equal to the acceleration due to gravity.B. a→ is equal to the instantaneous rate of change in velocity.C.a→ is perpendicular to the bob's trajectory.D. a→is tangent to the bob's trajectory.

As the pendulum approaches or recedes from which position(s) is the acceleration vectora→almost parallel to the velocity vectorv→?A. position 2 onlyB. positions 1 and 2C. positions 2 and 3D. positions 1 and 3
