Question

A 2.00 Kg pendulum bob on a string 1.20 m long is released with a velocity of 3.00 m/s when the support string makes an angle of 30.0 degrees with the vertical. What is the velocity of the swing?

A. 3.49 m/s

B. 4.00 m/s

C. 4.32 m/s

D. 3.75 m/s

Step 1

According to the conservation of energy, the total energy at a height is equal to the total energy at the bottom of the swing.

Step 2

Substitute the values in the above relati...
