Find mathematically the magnitude and direction of a fourth force F4 that will maintain the object at equilibrium. Ignore the weight of the object. Provide free body diagram for the system and the sum of the forces along the axis.A modification to an Atwood's Machine is to put one of the masses on a sloped surface (see diagam below). Two blocks are connected by a string as shown in the diagram. One mass m, = 3.50 kg is on the surface with negligible friction. This surface makes an of angle 30.0° with the horizontal.

- In Figure (a), a constant horizontal force F is applied to block A, which pushes against block B with a 21.0 N force directed horizontally to the right. In Figure (b), the same force is applied to block B; now block A pushes on block B with a 13.0 N force directed horizontally to the left. The blocks have a combined mass of 12.0 kg. What are the magnitudes of (a) their acceleration in Figure (a) and (b) force F. ? (a) Number i (b) Number i A B (a) Units Units BA (b)Consider an object at rest on a rough horizontal surface. Which of the following is necessarily correct if we use the model of friction described in the videos and book? The force of friction on the object is smaller than or equal to μg FN, where μs is the coefficient of static friction and FN is the normal force exerted on the object by the surface. The force of friction on the object is proportional to the normal force exerted by the surface on the object. The force of friction on any object opposes motion; since the object is at rest, the force of friction is zero. The force of friction on the object is proportional to the object's weight, i.e. Ff = p.mg, where μs is the coefficient of static friction, m is the mass of the object, and g is acceleration due to Earth's gravity.A woman exerts a horizontal force of 111 N on a box with a mass of 31.7 kg.

- A car of mass m₁ 1000 kg is connected to a trailer of mass m2 = 400 kg by a taut inextensible cable. The car's engine provides a constant forward driving force Fx = 7000 N, which causes the car-plus-trailer to accelerate forwards along the horizontal x-axis. The tension of the cable produces a force on the trailer and also a force on the car. You may assume that the magnitude of the two forces is the same. You may also ignore friction. What is the tension in the cable joining the car to the trailer?
