An elevator with a person in it is being pulled upwards by a massive cable. Identify all interaction forces (consistent with Newton's 3rd Law) in the system. Specify the object the force acts on. a label for its magnitude and its direction. Consider your system to consist of the cable, the elevator, the Earth and the person. For example, the Earth pulls down on the elevator with force Melevator9 and the elevator pulls up on the Earth with force Meievatorg?-...
2. The figure shows a 7 kg block being pulled along a frictionless floor by a cord that applies a force of constant magnitude 16 N but with an angle 0 (t) that varies with time. (a) for an angle e, draw a free-body diagram showing the forces applied to the block, and find expressions for the x & y components of the force on the block. (b) When angle 0 = 27°, find the block's acceleration. When angle 0...
Two blocks that are both 7 kg are connected by a string that massless and frictionless. The are both being pulled by a pulley over the edge of a table. A. If force is directed to the right and has magnitude 90 N, find the acceleration of the two blocks. B. For the same direction of F and magnitude, find the tension in the string. C. Now a different force, still horizontal, is applied to block A, making the tension...
A heavy sled is being pulled by two people as shown in the figure. The coefficient of static friction between the sled and the ground is As-0603, and the kinetic friction coefficient is μ< : 0.411. The combined mass of the sled and its load is m-351 kg. The ropes are separated by an angle φ = 25°, and they make an angle θ = 31.1° with the horizontal. Assuming both ropes pull equally hard, what is the minimum rope...
