Question

A 0.60 kg object is suspended from the ceiling at the end of a 2.0 m string. When pulled to the side and released, it has a speed of 4.0 m/s at the lowest point of its path. What maximum angle does the string make with the vertical as the object swings up?

Step 1

The energy is conserved. Thus,

Step 2

Thus, the height is given by,

Step 3

The expression for the height at which the object r...
