Problem 8: A horizontal force of magnitude F = 45 N pushes on a block of mass m = 4.01 kg. The block is on a frictionless incline that makes and angle 6 = 30.! degrees with horizontal. Part (:1) Write an expression for the acceleration ax of the block, taking up the ramp to be the positive x direction. Express your answer in terms of F, m, a, and g (9.30 mfsz). Expression ' x = Select from the variables below to write your expression. Note that all variables may not be required. tsll. eos(q)), (305(0), sin(u), sinp). sin(0), Ii, 1, 0. d, F, g. h, m, [I Part (b) What is the acceleration of the block in units of meters per seconds squared? Numeric : A numeric value is expected and not an expression. ux= mfs2 Problem 9: The diagram shows a crate of mass m =2 kg on a frictionless inclined plane that makes an 11 angle, 6 :22 , with the horizontal. A coordinate system is provided. A force of magnitude F , parallel to and directed up the plane. is applied to the crate. The crate moves up the plane with constant velocity. In numeric responses, use 9.80 m / s2 for the acceleration due to gravity. 7 \\9 Part (:1) Write an expression for SF}, the net force in the :c direction. Your expression should be in terms of F , m. g, and 9. Expression BF; = Select from the variables below to write your expression. Note that all variables may not be required. 90801).
