A 1.34 kg ball is connected by means of two massless strings, each of length L =1.70 m, to a vertical rotating rod. The strings are tied to the rod with separation d =1.70 m and are taut. The tension in the upper string is 35 N.
(a) Draw the free body diagram for the ball, and label the r ˆ-direction in the diagram. (Please use either a polar or cartessian coordinate system & please show r direction as well)
(b) Write down Newton’s 2nd law for the ball along the two axes in your free body diagram (a convenient set is the y -axis and the r ˆ-direction).
(c) What is the tension in the lower string?.

A 1.34 kg ball is connected by means of two massless strings, each of length L = 1.70m, to a vertical, rotating rod. The strings are tied to the rod with separation d=1.70 m and are taut. The tension in the upper string is 35 N. a) Draw the free body diagram of the ball. Choose an appropriate set of axes (explain your choice) and draw a component diagram with respect to the axes you have chosen. What are the:...

3. A 1.29 kg ball is connected by means of two ideal strings to a horizontal, rotating rod. The strings are tied to the rod and are taut. The right string is 26.0 cm long and has a tension of 29.3 N, and it makes an angle 02 = 50.0° with the rod, while the left string makes an angle 01 = 64.0° angle with the rod. At the instant shown the ball is at its highest point. (a) What...
The 4.00 kg block in the figure is attached to a vertical rod by means of two strings.
The 4.00 kg block in the figureis attached to a vertical rod by means of two strings. When the system rotates about the axis of the rod, the strings are extended as shown, and the tension in theupper string is 80.0 N. (a) What is the tension in the lower cord? Start with a free body diagram of the block. (b) What is the speed of the block?

A yo-yo of mass m and radius R is placed on a horizontal surface as shown. A massless string is wrapped around an axle of radius r. The string will be pulled horizontally to the right as shown with a force of constant magnitude F. There is sufficient friction (f) between the surface and the yo-yo for the yo-yo to roll without slipping. Assume that the moment of inertia of the yo-yo about its rotation axis is approximatelyI (1/2)mR2. Draw...

Two basketballs, one regulation and one heavy ball (regulation basketball has mass of 0.624 kg while the heavy ball has mass of 1.359 kg are tied to each other by a light string (light string means you need not consider the mass of the string). The regulation ball is above the heavy ball and a player holds the regulation ball in his palm. Draw the free body diagram(s) appropriate for the situation and then calculate the force that the player...
