At what angle theta ?with respect to the vertical does the magnet hang? Consider the same situation as in the previous problem. This time the magnet has mass 6.62 kg and the force pulling the magnet to the right has magnitude 180.6 N. What is the magnitude of the tension force in the cord? Same situation as in the previous problem this time the magnet has mass 7.25 kg, the force pulling it to the right is 111.3 N, the cord has length 0.54 m and the ceiling is 2.82 m above the floor. How far to the right of its start point will the magnet have traveled when it hits the floor after the cord is cut? OK, one more time.

- In the diagram shown, mass 1 (m1) is 18.79 kg and the coefficients of static and kinetic friction are 0.31 and 0.18, respectively. What is the maximum mass that mass 2 (m2) can have for the system to remain at rest? Assume that the pulley shown is ideal, massless, and frictionless. m2 = kgTwo masses mA =9.3kg and mB=6.1kg are on inclines and are connected together by a string as shown in the figure. The angles theta subscript A=700 and theta subscript B = 360 . In the absence of the friction, the force F is required to pull the masses at a constant velocity up the fixed inclines. The force F is now removed. What is the magnitude of the acceleration of the two blocks? Take g =9.81 m/s2, and express your answer using two decimal places.A block of mass M1 = 3 kg rests on top of another block of mass M2 = 5 kg.
