I have a problem that I've tried to figure out, but I can't figure it out.
Here it is:
You whirl a ball of mass 0.40 kg on a string of length 0.90 m. At the point shown the angle of the string from the vertical is 30 degrees and the ball has a speed of 3.5 m/s.
a) Make a free body diagram of the ball.
b) Find the tension in the string.
c) What is the acceleration of the ball, tangential and radial components?
c) Now consider the ball at the top of the circle. What is the smallest speed of the ball so that the ball continues in a circle?
Any help with this problem would be greatly appreciated!
