1. (20 points) A pendulum consists of a small ball of mass m=2.00 kg that is suspended from a fixed point by a light string of length L=0.850 m (like the demonstration video.) The pendulum is released from rest when it is in its initial position with 0 =65.0°. Air resistance is negligible. a) Calculate the work done by gravity as the ball moves from the highest point of its semicircular path to the lowest point of its path. b)...

1. A 9.6 kg particle is attached to a rope of length L. 1.7 m. It is released from the horizontal position A, and it swings as a pendulum. Once the particle reaches point B (a distance h 1.2 m below), you push horizontally on the particle with a varying force F such that it slows down and comes to rest at the lowest point C a. Calculate the speed of the particle at point B. b. Calculate the...

A pendulum consists of a 2.5-kg bob attached to a light 1.2 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 3m/s. At the instant the string makes an angle of 38 degree with the vertical, what is The speed, The tension in the string? What is the angle of the string with the vertical when the bob reaches its greatest

6) A 0.25 kg mass is hanged from a string with length L = 0.65 m, making a pendulum. The mass is raised so that the taut string makes an angle of θ = 37◦ with the vertical, and then released from rest. When the mass swings past the bottom (where its speed is maximum) it is observed to have a speed of 1.1 m/s. a) Choosing the bottom as your h = 0 level, what is the initial height...

The pendulum shown to the left consists of a bob of mass of 0.44
kg, attached to a string of length L = 1.2 meters. It is
moving to the right with a speed of 4.62 m/sec at point A. What
we'd like to know is what the the velocity of the bob when it
reaches point B which is 36 degrees from vertical.
There are two different ways to look at this problem, each of
which will give us...

NEED ASAP A pendulum is made up of a massless rod of length 1.6 m attached to a 4 kg mass. It’s released from rest when the pendulum is horizontal. When the pendulum is vertical, the mass is moving at 4.8 m/s. a) Taking the gravitational potential energy to be zero at the bottom of the swing, what is the initial total mechanical energy? b) How much energy is lost due to air resistance as the pendulum moves from its...

A pendulum bob, with mass 1.60 kg, is held at rest initially in a horizontal position as shown. The string has negligible mass and a length of 1.20 m. The bob is then released from rest. It swings down and collides with a block of mass 2.40 kg initially at rest. Ignore air resistance. a) Use the Principle of Conservation of Mechanical Energy to find the speed of the pendulum bob just before the collision. b) (The bob collides with...

Background/ Introduction 1. A small weight at the end of a string of length, L, forming a simple pendulum. 2. A horizontal rod is located a distance, d, directly beneath the pivot point. 3. The mass is held so that the string is taut and horizontal and then let fall. 4. What is the minimum distance, d, such that the mass will cause the string to loop over the pin at least In theory, we assume the bob is a...

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)...
