(10%) Problem 6: A crate of mass m = 0.91 kg is on a frictionless incline that makes an angle of 0 = 21.8 degrees with horizontal. A force of magnitude P = 7.25 N is applied to the crate in a direction parallel and up the incline, as shown. 9 25% Part (a) Write an expression for the acceleration ax of the crate, where positive x is up the incline. Your answer should be in terms of m, P, 19, and g (9.80 m/s2). (10%) Problem 8: The free-body diagram shows the all of the forces acting on an object of mass m = 4.58 kg, The three forces have magnitudes F1 = 13.1 N, F2 = 25.8 N, and F3 = 12.6 N, with y directions as indicted in the diagram, Where 0 = 43.5 degrees. E A 25% Part (a) Write an expression for the x-component of the acceleration in terms of the symbols in the problem statement.
