Question: A ball is attached to the end of a string. It is swung in a vertical circle of radius 0.33 m. What is the minimum velocity that the ball must have to make it around the circle?

P-2 Please I need help with this question needed a very clear and step-by-step explanation and needed with clear handwriting please, will be really appreciated your help.

Need help with graphic motion

The diagram below shows a mass that is oscillating on the end of a string at three different times t₁, t2, and t3 during a single cycle. At t, it is at maximum displacement in the negative direction. In the following questions we will disre- gard the centripetal acceleration of the bob due to its circular motion about the point O. a. Draw the velocity and acceleration vectors next to the pendulum bob at times t₁, t2, and t3 to show the direction and relative magnitude of those vector quantities at those positions. The vectors at time t₁ have already been drawn. Note: The centripetal acceleration that arises from the circular motion about O is neglected. Draw the forces acting on the bob at each of those instants. 11 a V At which instant t₁, t2, or t3 does the bob have the greatest velocity? What is the acceleration at that position? Explain. b. C.
