The two forces F⃗1 and F⃗2 shown in the figure (Figure 1) (looking down) act on a 20.0-kg object on a frictionless tabletop. Part A If F1=12.0 NN and F2=18.0 N, find the magnitude of the net force on the object for (a).   Part B Find the direction of the net force on the object for (a).   Part C Find the magnitude of the acceleration of the object for (a).     Part D Find the direction of the acceleration of the object for (a).

Only two horizontal forces act on a 6.8 kg body. One force is 7.9 N, acting due east, and the other is 6.6 N, acting 40° north of west. What is the magnitude of the body's acceleration? Number i Units

The two trees in (Figure 1) are 7.1 m apart. A backpacker is trying to lift his 29-kg backpack out of the reach of bears. Part A Calculate the magnitude of the force F that he must exert downward to hold the backpack so that the rope sags at its midpoint by 1.3 m.

y Problem 3: The diagram shows the all of the forces acting on a body of mass 2.31 kg. The three forces have magnitudes F₁ = 50.6 N, F2 = 20.8 N, and F3 = 75.8 N, with directions as indicted in the diagram, where 0 = 39.6 degrees and p = 30.1 degrees. The dashed lines are parallel to the x and y axes. At t = 0, the body is moving at a speed of 7.93 m/s in the positive x direction. Part (a) What is the x component of the acceleration in m/s²? ax = || Ę Lª F $ F
