- The figure below shows a block with mass m = 5.1 kg pulled up a ramp inclined at an angle of ? = 28° with a force of magnitude F = 33 N parallel to the ramp. (a) If there is no friction between the block and the ramp, what is the magnitude of the block's acceleration (in m/s2)? m/s2 (b) If instead the coefficient of kinetic friction between the block and the ramp is 0.11, what is the magnitude of the block's acceleration (in m/s2)? m/s2A cord passing over a pulley connects two masses, as shown, where m, 3.70 kg and m₂ 6.50 kg. The system accelerates with a magnitude of 1.11 m/s². The coefficient of kinetic friction between the masses and the incline is the same for both masses. Assume the pulley is frictionless, and the cord is massless. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) 35.0 (a) What is the coefficient of kinetic friction? (b) What is the tension (in N) in the cord?For the next three items: A 200 kg plank is projecting a distance L = 5.0 m from a wall which is held steadily by a string that is connected to it at an angle = 30° from the horizontal.
