How hard must each player pull to drag the coach at a steady 2.0 m/s?
A box weighing 50 N rests on a horizontal surface. A person pulls with a force of 10N to the right and it does not move. In order for you to move, you need another person who pulls vertically. What is the minimum force that the other person needs to exert in order for it to move? Coefficient of static friction = 0.4
A girl has a 14 kg wagon. If she pushes from behind at an angle of the 30 degrees with a force of 60 N, she finds she can push the sled with a constant speed when she pulls on the handle, it makes an angle of 30 degrees to the ground. If she pulls with the same force, how fast will the wagon accelerate?
a girl is pulling her 6.8kg wagon along a horizontal sidewalk. the force exerted by the girl is 17 N at an angle of 20 degrees above horizontal. what is the normal force?
A football coach sits on a sled while two of his players build their strength by dragging the sled across the field with ropes. The friction force on the sled is 1500 NN and the angle between the two ropes is 20 ∘∘. Assume both players pull with the same force. How hard must each player pull to drag the coach at a steady 2.0 m/s?
Tim got a huge birthday gift from his grandmother. A 400. N crate has been delivered to his driveway. In order to get it started moving toward his door, he has to push it with a horizontal force of 250 N, but as soon as it is moving, he can keep it moving at a constant speed by pushing with a 120 N force. What are the coefficients of static and kinetic friction of Tim's birthday gift and the driveway?
Lauren pulls her 18 kg suitcase at a constant speed by pulling on a handle that makes an angle of θ with the horizontal. The frictional force on the suitcase is 27 N and Lauren exerts a 43 N orce on the handle. a) What angle does the handle make with the horizontal? b) What is the normal force exerted on the suitcase?
Magnus has reached the finals of a strength competition. In the first round, he has to pull a city bus as far as he can. One end of a rope is attached to the bus, and the other is tied around Magnus's 48 in waist. If a force gauge placed halfway down the

Siri is exerting a 36-N horizontal force as she pulls a 52-N sled across a cement sidewalk at a constant speed. What is the coefficient of kinetic friction between the sidewalk and the metal sled runners? Ignore air resistance.
An early submersible craft for deep-sea exploration was raised and lowered by a cable from a ship. When the craft was stationary, the tension in the cable was 6500 N. When the craft was lowered or raised at a steady rate, the motion through the water added an 1800 N drag force. What was the tension in the cable when the craft was being lowered to the seafloor?
Santa Claus tries to drag his bag of presents along a horizontal surface by a red rope that is angled at 55 degrees above the horizontal. Santa Claus applies a force due to tension of 4500N along the red rope. This is the minimum force to just start the bag in motion. The coefficient of kinetic friction between the bag and the ground is 0.3 and the coefficient of static friction is 0.5. What is the mass of the bag?
