1)A loudspeaker of mass 19.0 kg is suspended a distance of h = 2.40 m below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.70 m .What is the tension T in each of the cables?Use 9.80m/s^2 for the magnitude of the acceleration due to gravity.2)It's a snowy day and you're pulling a friend along a level road on a sled. You've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. You've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 45.0 angle. You estimate that the mass of the sled, with your friend on it, is 75.0 kg and that you're pulling with a force of 79.0N .What answer will you give?3)A chair of weight 70.0 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 41.0 N directed at an angle of 41.0 below the horizontal and the chair slides along the floor.Using Newton's laws, calculate n, the magnitude of the normal force that the floor exerts on the chair.Express your answer in newtons.
