OK, once again we have a pendulum, this time of length 1.14 m, which you release from rest at an angle of 55.7 degrees to the vertical. What will be the speed of the pendulum at the instant it reaches an angle of 22.3 degrees above the vertical? A 3.12 m/s B 1.29 m/s C 3.74 m/s D 2.84 m/s

A simple pendulum swings back and forth in a circular path. Including the effects of air resistance, determine which statement is true. There may be more than one correct answer. A. After the pendulum is released, it will never return to its original height. B. The total linear acceleration vector always points towards the center of the circular path as the pendulum swings back and forth. C. The work done by air resistance is always negative as the pendulum swings back and forth D. The work done by the tension force is always zero as the pendulum swings back and forth E. The gravitational force always produces a counterclockwise torque as the pendulum swings back and forth.

7. The spring is compressed by the mass (m= 2 kg) to half of its original length and then released. The surface is not smooth and has coefficient of friction 0.2. What will be its speed after 2 s. The spring constant is 200 N/m and the unstretched length of the spring is 60 cm.The mass is not connected to the spring and it can slide on the surface after it is released after compression. k m x = 0

1. A simple pendulum is suspended from the ceiling by means of a string of length 1.14 m. Assume that there is no friction or air resistance. Suppose you were to release the pendulum from rest, starting from an angle of 58.2 degrees with respect to the vertical, as shown. What will be the speed of the pendulum at the instant it swings through its lowest point (that is, when it s momentarily hanging vertically)?      2.28 m/s      3.25 m/s      3.43 m/s      4.73 m/s

QUESTION 3 This, the length of the pendulum is 1.03 m. Now you start with the pendulum at 28.7 degrees with respect to the vertical, but rather than releasing it from rest, you give it a push downward. It swings to the other side, and reaches a maximum angle of 47.8 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it?   A 2.04 m/s   B 2.58 m/s   C 1.58 m/s   D 3.61 m/s

The pendulum shown in the figure below is released from point A starting from rest. The length of the cord is 75 cm and the mass of the ball is 1 kg. Find the speed of the ball as it passes through point C. Find the speed of the ball at point b.

3. A 60 kg snowboarder begins to slide down the hill 50 m high on a smooth surface with a radius curvature of 80 m. The next section (AB) is a 20 m flat rough track with u = .3, at the end of which there is an elastic barrier with k = 1000 N/m. Find her speed at point A. b. How much work is done by frictional force? c. What is the maximum compression of the spring? d. Find the rate of heat dissipation along the section AB. e. How long does it take to cover the section AB? а. h k В

After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 46.0 cm. The explorer finds that the pendulum completes 96.0 full swing cycles in a time of 145 s. What is the magnitude of the gravitational acceleration on this planet? Express your answer in meters per second per second. If we use idea of simple pendulum, such that the period or T = square root of the length/g cycles, I believe that 2 pie when when get rid of square root makes 2 pie become 4 pie.  Please the math steps in detail where g= 4pie^2/T^2 I need to get the steps right, so I can use 2pie*sqare riit if L/G

This, the length of the pendulum is 1.89 m. Now you start with the pendulum at 8.5 degrees with respect to the vertical, but rather than releasing it from rest, you give it a push downward. It swings to the other side, and reaches a maximum angle of 42.5 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it?     4.99 m/s     3.06 m/s     3.12 m/s     0.64 m/s

3) OK, once again we have a pendulum, this time of length 1.94 m, which you release from rest at an angle of 59.1 degrees to the vertical. What will be the speed of the pendulum at the instant it reaches an angle of 29.6 degrees above the vertical? Question 2 options:   6.88 m/s   3.68 m/s   4.30 m/s   2.23 m/s 4) This, the length of the pendulum is 2.17 m. Now you start with the pendulum at 10.2 degrees with respect to the vertical, but rather than releasing it from rest, you give it a push downward. It swings to the other side, and reaches a maximum angle of 34.0 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it?   2.70 m/s   0.82 m/s   3.51 m/s   2.57 m/s
