Question

A conical pendulum is formed by attaching a 0.30kg  ball to a 1.0m -long string, then allowing the mass to move in a horizontal circle of radius 40cm . The figure (Figure 1) shows that the string traces out the surface of a cone, hence the name.

a. What is the tension in the string?

b. What is the ball's angular velocity, in rpm?
