3. A block of miss me = 1,80 ks on a rough inclined surface (30" from horizontal) is connected to a ball of mass nu - 1.50 kg by a lightweight cord over a lightweight. frictionless pulley as shown. A force of magnitude F = 30.0 N at an angle e = 25.0" with the surface is applied to the block and the block slides to the right. The coefficient of static and kinetic friction between the block and surface are its = 0.465 and ux = 0.364 respectively. [Answer in 3 significant figures] al Draw the free body diagram for both my and ma. (include Cartesian coordinate system) b) Write down Newton 2nd Law EF, and EF, with correct force components for both mass n and mass my separately. c) What is the magnitude of the acceleration of the two objects? d) What is the tension of the rope? e) What is the range of the applied force F that will keep both blocks from moving upward? [Note: block 2 must sit on the incline at all time] |
