Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A force of 16 . 82 N pushes and pulls to blocks as shown in the figure below. The vertical contact surfaces between the two blocks are frictionless. The contact between the blocks and the horizontal surface has a coefficient of friction of 0 . 29. The acceleration of gravity is 9 . 8 m / s 2 . 2 . 9 kg 5 . 8 kg F F 5 ◦ μ k = 0 . 29 a What is the magnitude a of the acceleration of the blocks? Answer in units of m / s 2 . 002 10.0 points Three blocks in contact with each other are pushed across a rough horizontal surface by a 110 N force as shown. The acceleration of gravity is 9 . 8 m / s 2 . 2 kg 7 . 9 kg 3 . 5 kg F μ = 0 . 17 If the coefficient of kinetic friction between each of the blocks and the surface is 0 . 17, find the magnitude of the force exerted on the 7 . 9 kg block by the 3...
