... Problem 1. A block of mass m = 2 kg resting on a rough horizontal surface is pushed by a force F = 10 Newtons that acts along a direction 37 degrees below the horizontal as shown. The block moves at a constant velocity v = 5 m/s. (a) (8 pts) What is the net force on the block? ANSWER: F_net = 0, sin ...

... The weight of the arm is W, the tension in the horizontal cable is T and the force exerted on the arm at the hinge is R. (i) Calculate the tension T in the horizontal cable. The arm is held stationary, i.e. it is in equilibrium. There is no resultant force and no resultant torque acting on the arm. ...
