When the Moon is directly overhead at sunset, the force by Earth on the Moon, FEM , is essentially at 90° to the force by the Sun on the Moon, FSM , as shown below. Given that FEM = 1.98 × 1020 N and FSM = 4.36 × 1020 N, all other forces on the Moon are negligible, and the mass of the Moon is 7.35 × 1022 kg, determine the magnitude of the Moon’s acceleration.

Two thieves want to steal a 1mx1mx1m Lazada Mystery Box worth of 1million pesos that is placed on a warehouse with a cemented floor. When they successfully break into the warehouse using a bobby pin they realize that they both cannot carry the 400 lb package, so they decided to push it out of the warehouse. If the untouched package and the cemented floor has a coefficient of friction of 0.400, what is the maximum amount of force they first need to exert in order to make the package move when they will: A) push the package with their hands 90 degree with the vertical wall of the box. B) push the package with their hands in 120 degree with the vertical wall of the package. C) When they decided to pull the box instead and their hands are in 120 degree with the top edge of the box.

In the figure provided, a crate of mass m sits at rest on a 20° ramp and is connected to another crate of mass 1.84 kg by a rope and pulley. If the coefficient of friction is μk = 0.510 and μs = 0.790 with the surface, what acceleration will the mass m have if it is slightly nudged and begins to be pulled up the ramp? Assume the rope and pulley are massless.
A block with a mass of m = 22 kg rests on a frictionless surface and is subject to two forces acting on it. The first force is directed in the negative x-direction with a magnitude of F1 = 12 N. The second has a magnitude of F2 = 18.25 N and acts on the body at an angle θ = 19° measured from horizontal, as shown. Write an expression for the magnitude of the normal force, FN, acting on the block, in terms of F2, g, and the other variables of the problem. Assume that the surface it rests on is rigid. Write an expression for the component of net force, Fnet,x, in the x-direction, in terms of the variables given in the problem statement. Part (d) Find the block's acceleration in the x-direction, ax, in meters per second squared.
A block of mass m1 = 14.5 kg is on a frictionless table to the left of a second block of mass m2 = 22.0 kg, attached by a horizontal string.
