3) Find the Tension in the 3 different strings if the rock has a weight of 40N. B) Draw a FBD of the rock and knot 4) A 5-kg mass hangs at the end of a cord. Find the tension in the cord if the cord is accelerated at a) 1.7 m/s up (b) 1.3 /s2 down 5) A 15-kg mass hangs from one end of a rope that passes over a pulley. A 28-kg is suspended from the other end of the pe. (A) What is the magnitude of acceleration of each of the masses? (B) What is the tension in the rope? 6) Two blocks are connected by a string over a pulley. The hanging block has a mass of 8-kg and the one on the plane is a mass of 2-kg. The coefficient of kinetic friction is mk = .23. (A) What is the acceleration of the blocks? (B) What is e tension in the string connecting the blocks? 7) Two blocks are connected by a string over a pulley. The hanging block has a mass of 8-kg and the one on the plane is a mass of m2. If the coefficient of static friction is .8 what is the minimum mass that my must be in order for the
