The diagram shows the all of the forces acting on a body of mass 2.76 kg. The three forces have magnitudes F1 = 65.2 N, F2 = 21.6 N, and F3 = 77.9 N, with directions as indicted in the diagram, where θ = 49.9 degrees and φ = 21.1 degrees. The dashed lines are parallel to the x and y axes. At t = 0, the body is moving at a speed of 6.87 m/s in the positive x direction.
a. whats the x component of the acceleration?
b. whats the y component of the acceleration?
c. whats the speed of the body in m/s at t = 12.3s?
d. whats the magnitude of the displacement of the body n meters between t = 0 and 12.3s?
