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. What are the (a) tension in the lower string, (b) magnitude of the net force  on the ball, and (c) speed of the ball? (d) What is the direction of the net force?

A 4 kg block is sliding down a vertical wall while being pushed by an external force as shown in the figure. What magnitude of the external force (in N) would be required for the block to move down the wall at constant speed if the coefficient of kinetic friction between the wall and the block is u = 0.20? 4 kg 六F 300 36.98

A 2.00 kg aluminum block and a 6.00 kg copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle θ=30.0∘θ=30.0∘) with the aluminum block on the flat of the wedge and the copper block on the angled part. Determine (a) the acceleration of the two blocks and (b) the tension in the string.

CM4: A 58 kg circus performer hangs from a bar suspended from a ceiling as shown in the figure. If the bar masses 12 kg (and its weight acts at its center) and has a length of 1.4 m, what is the tension T₂ in the rope? The rope is attached 0.85 m along the bar. تل T₂ 50°

The crate A weighs 780 lb. Between all contacting surfaces, μs = 0.34 and μk = 0.29. Neglect the weights of the wedges. What force F is required to move A to the right at a constant rate? Wedge angle is 6 degrees.

A 30.6 kg mass (m) is suspended by the cable assembly as shown in the figure. The cables have no mass of their own. The cable to the left (T|) of the mass makes an angle of 0.00° with the horizontal, and the cable to the right (T2) makes an angle (02) of 36.4°.
