There are two forces on the 1.19 kg box in the overhead view of the figure but only one is shown. For F1 = 15.7 N, a = 14.7 m/s2, and θ = 34.1°, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) a direction. (State the direction as a negative angle measured from the +x direction.)
A block of mass m1 is placed on top of a block of mass m2. You push the two blocks so that they move up a vertical wall, with a constant force of magnitude P directed at angle theta. The coefficient of friction between m2 and the wall is u. There is no friction between the blocks and no friction between m1 and the wall. Find the force exerted by the lower block on the upper block. The answer the book gives me is (P(cos(theta)-u*sin(theta)))/(1+(m2/m1)) I get how to get the numerator but am unsure of how the denominator answer was gotten and where gravity went in the equation

Using the same force table that you used, a student was given two forces and asked to find a single force that would produce equilibrium with the two forces. The two forces were given by providing one of the components and the angle the force made with the positive x- axis. The two forces were as follows: Force 1: Fx = −2.70 N; Theta = 220.0 degreees Force 2: Fy = 3.20 N; Theta = 60.0 degrees (a) For each force, calculate the magnitude of the force and the mass required to produce it. (b) Calculate the mass and its angle of application to produce equilibrium with these two forces. Please specify your angle as counterclockwise positive with respect to the positive x-axis.
