1am playing tug-o-war with my three nephews. The youngest in pulling with a force of 189 N. The middle child is pulling with a force of 334 N. The oldest is pulling with a force of 657 N. I am on a team with the youngest child. If I want to keep the four of us in equilibrium, how hard (in newtons) must I pull?

A warehouse worker applies a force F to accelerate two crates, mã and mp, to the right along a rough floor. Crate mд has a mass of 4m, crate mp has a mass of m. Choose 1 answer: A F Which is the correct relationship between the applied force F acting on mд and the force mд exerts on mB? B D MA mB The force Facting on my is smaller than the force that mA exerts on MB. The force Facting on my is the same as the force that mA exerts on MB. The force Facting on my is larger than the force that mд exerts on MB. The answer depends on the relative size of the friction force on MA and MB.

A worker at the LAX airport is pulling a 31.8 kg suitcase across a flat floor. The force that the worker exerts is constant (F=47 N) at an angle above 77.5 degrees above the horizontal. What is the normal force of the suitcase as it moves across the floor?

A man stands on a scale in an elevator that is accelerating upward. The scale reads 973.8 N. When he holds a 44.0 kg box, the scale reads 1449.8 N. What is the man's mass? and What is the magnitude of the acceleration of the elevator?

A box is placed on a rough floor. When you push horizontally against the box with a 40N force, the box just begins to slide. What is the magnitude of the friction force when you push against the box with a 25 N force? O58 N O 15 N O 40 N 98 N O none of the answers O 25 N

Two skaters are on an icy pond (no friction). They have masses m1 = 65.0 kg and m2 = 80.0 kg. They are each holding one end of a rope. The heavier skater starts exerting a force of F = 125 N. The rope tautens so that it has a tension T. What is the acceleration of each skater, and what is the tension in the rope?
