A ball of mass 2.0 kg is attached to the end of a 2.2 m long string and whirled around in a circle thatdescribes a horizontal plane.a. What is the frequency of rotation of the ball if the string makes an angle of 15◦ with respect to the vertical?Provide a free-body diagram.
b. At this speed (solved from part a), what is the tension in the string?
Help! Hi, please someone explain the free-body diagram? How did you arrive at that fbd?
Please explain clearly in a paragraph!
will give a thumbs up!
I would like to know if you can break down step 2 part b
I know it has to do with some trigonometry, but how do you set up the equation? Like can you do a free body diagram, and explain a little bit more detail?

The blocks have masses m1 = 3kg and m2 = 15kg.(a) How hard are you pushing on m1, if the acceleration of m2 is 6m/s2? (You are pushing horizontally, as shown in the figure.) (b) What is the contact force between m1 and m2? (Still focusing on the figure on the left.) (c) Now consider the figure on the right, in which m2 is lifted off the ground. If the coefficient of static friction between m1 and m2 is 0.2 how hard would you have to push the blocks to ensure m2 would not slide down m1?arrow_forward
