Only two horizontal forces act on a 7.7 kg body. One force is 7.0 N, acting due east, and the other is 4.3 N, acting 40° north of west. What is the magnitude of the body's acceleration?

Three astronauts, propelled by jet backpacks, push and guide a 133 kg asteroid toward a processing dock, exerting the forces shown in the figure, with F₁ = 27 N, F₂ = 54 N, F₃ = 38 N, θ₁ = 30°, and θ₃ = 60°. What is the (a) magnitude and (b) angle (measured relative to the positive direction of the x axis in the range of (-180°, 180°]) of the asteroid's acceleration?

The figure shows a box of dirty money (mass m₁ = 4.5 kg) on a frictionless plane inclined at angle θ₁ = 23°. The box is connected via a cord of negligible mass to a box of laundered money (mass m₂ = 1.5 kg) on a frictionless plane inclined at angle θ₂ = 53°. The pulley is frictionless and has negligible mass. What is the tension in the cord?
