A simple pendulum is suspended from the ceiling by means of a string of length 2.47 m. Assume that there is no friction or air resistance. Suppose you were to release the pendulum from rest, starting from an angle of 32.4 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)? A 1.65 m/s B 2.75 m/s C 6.40 m/s D 6.96 m/s

OK, once again we have a pendulum, this time of length 1.86 m, which you release from rest at an angle of 52.5 degrees to the vertical. What will be the speed of the pendulum at the instant it reaches an angle of 10.5 degrees above the vertical?     3.78 m/s     0.78 m/s     5.67 m/s     3.70 m/s

OK, once again we have a pendulum, this time of length 1.49 m, which you release from rest at an angle of 41.6 degrees to the vertical. What will be the speed of the pendulum at the instant it reaches an angle of 12.5 degrees above the vertical?     4.08 m/s     2.58 m/s     2.72 m/s     0.83 m/s

An object is attached to a light string and is forced to move in uniform circular motion on a frictionless table. The radius of the circular path is 0.5m and the maximum amount of tension the rope can withstand without breaking is 16N. What is the maximum amount of kinetic energy this object can have?

A 215 g object is attached to a spring that has a force constant of 75.5 N/m. The object is pulled 9.25 cm to the right of equilibrium and released from rest to slide on a horizontal, frictionless table.   Calculate the maximum speed vmax of the object.

2. A simple pendulum is suspended from the ceiling by means of a string. this time of length 2.33 m, which you release from rest at an angle of 45.4 degrees to the vertical. What will be the speed of the pendulum at the instant it reaches an angle of 36.3 degrees above the vertical?      2.18 m/s      3.69 m/s      2.98 m/s      5.17 m/s

A block of mass m=1.2 kg is attached to a horizontal spring of force constant k=75 N/m. The block is pushed, and spring is compressed, to the position 10.0 cm to the left of the equilibrium position; then, block is released. A. Neglect friction. Find the speed of the block as it passes through the equilibrium position. B. If the friction is significant and µ = 0.22, what is the speed of the block as it passes through the equilibrium position? Please show the detailed solution, Thank you

A simple pendulum is suspended from the ceiling by means of a string of length 2.49 m. Assume that there is no friction or air resistance. Suppose you were to release the pendulum from rest, starting from an angle of 37.3 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)?     6.23 m/s     6.99 m/s     2.21 m/s     3.16 m/s

Hello, can you solve the first 3 parts? Thank you!

A 7.0 kg block on a horizontal, frictionless surface is attached to a light spring (force constant = 1.2 kN/m). The block is initially at rest at its equilibrium position when a force of magnitude P acting parallel to the surface is applied to the block, as shown. When the block is 8.0 cm from the equilibrium position, it has a speed of 0.80 m/s. How much work is done on the block by the force P as the block moves the 8.0 cm? A. 7.4 J B. 5.4J C. 6.1J D. 6.7J E. 4.9J
