A 10-kg mass is suspended as shown in Fig. 4.41. What is the tension in the cord between points A and B?
Answer to relevant QuestionsReferring to Fig. 4.41, what are the tensions in all the cords? An Atwood machine (see Fig. 4.42) has suspended masses of 0.25 kg and 0.20 kg. Under ideal conditions, what will be the acceleration of the smaller mass? A 20-kg box sits on a rough horizontal surface. When a horizontal force of 120 N is applied, the object accelerates at 1.0 m/s2. (a) If the applied force is doubled, the acceleration will (1) increase, but less than double; ...A 5.0-kg block at rest on a frictionless surface is acted on by forces F1 = 5.5 and F2 = 3.5 N as illustrated in Fig. 4.33. What additional force will keep the block at rest? An object (mass 3.0 kg) slides upward on a vertical wall at constant velocity when a force F of 60 N acts on it at an angle of to the horizontal. (a) Draw the free-body diagram of the object. (b) Using Newton’s laws find ...
