Question # 4 a) In the figure below, a conical pendulum is hanging from a string that is 2.2 meters long. It makes a horizontal circle. The mass of the ball at the end of the string is 0.5 kg. Find the following: (10 Points) 1) Below, makes a free body diagram for the ball and label each force with an appropriate letter? 2) Write out Newton's Second Law in both the x- direction and y- direction in terms used in your free body diagram? 3) Calculate the centripetal acceleration from your free body diagram? 4) What is the radius of the circle that the ball is traveling in? 5) What is the speed of the ball? ball Horizontal Circle b) In the diagram below, two blocks m and M are connected by a pulley, the coefficient of friction force between the mass m and the tabletop is 0.25, while the masses of blocks m, M are 5 kg and 20 kg respectively. Find the following 1) Makes a free body diagram for the two blocks and label each force acting on each of them? 2) What is the tension force in the string? 3) What is the acceleration of the two blocks? m
