How do I answer these physics questions and what answer should I get?

Question

A 0.5 kg ball that is tied to the end of a 1.5 m light string is revolved in a horizontal plane, with

the string making a 30 o angle with the vertical.

(a) Draw the free-body diagram for a conical pendulum.

(b) Set the equations of motion for the ball.

(c) What is the ball’s speed?

(d) If the ball is revolved with 4.0 m/s speed, what angle the string make with the vertical?

(e) It the string can withstand a maximum tension of 9.8 N, what is the highest speed at which

the ball can revolve?

Hi Mike I.,

All your 3 co-submitted questions involve similar physical situations, namely uniform circular motion. Use the equation in the problem above.

It's not cool to submit multiple questions on essentially the same topic. Wastes tutor time.
