Cow force, Inclined plane Velocity, v B, slope DATA The coefficient of friction mu = 0.45 The initial velocity in the shown direction) is Vi = 50.8 ft/s stopping distance S = 27.4 feet USER SUPPLIED DATA FOR THE WEIGHT OF THE BOX = YOUR WEIGHT + YOUR HEIGHT IN INCHES Example - suppose your weight is 160 lbf and your height in inches is 170 inches, the weight W = 160 + 170 = 330 lbf FOR THE ANGLE...
(Newton's laws/gravitation force/normal force/friction force, 4/ea.) A 60-N force pushes two objects next to each other with masses m_1 = 8 kg, and m_2 = 4 kg, across a horizontal solid surface. As shown below, the force is directed 30 degree below the horizontal. The coefficient of kinetic friction is 0.15, same for both objects. What is the normal force on m_1? What is the normal force on m_2? What is the acceleration of the masses? What is the force...
1. A person exerts a horizontal force of 125 N on a crate with a mass of 30.0 kg. a. If the crate doesn't move, what's the magnitude of the static friction force? b. What is the minimum possible value of the coefficient of static friction between the crate and the floor? 2. A horse is hamessed to a sled having a mass of 236 kg, including supplies. The horse must exert a force exceeding 1.240 N at an angle...
Inclined Plane ProblemsProblem 1:Suppose, as shown in the figure, that a 70-kg box is pulled by a 400-N force at an angle of 30° to the horizontal. The coefficient of sliding friction is 0.50. Find the acceleration of the box.
Pushing a Chair along the Floor Part A - Normal force exerted on the chair by the floor Learning Goal: To understand the role of friction in a state of equilibrium. A chair weighing 150 N rests on a level floor that is not frictionless. A man pushes on the chair with a force F = 42.0 N that is directed at an angle of 36.0 with the horizontal.(Figure 1) Assume that the chair is stationary but is on the...
If an object has 45N of static friction and a normal force of 450. What is the coefficient of friction?
CALCULATIO Show all your work in the space provided below and transfer the results to the tables or results section 1. Calculate the weight, in Newtons, of the mass piled on the sled for lines 2-7 in the first data table. Add the weight of the sled to the weight on the sled to the normal force, N, for lines 1-7 of the first data table. Draw a graph of the data on lines 1-6, plotting "friction force" on the...
You are dragging your 30N sled up hill, using 5N of force. What is the coefficient of friction between the sled and snow? You weigh 800N and get on the sled at the top of the hill, how much force must your friend produce to push you from a stop if the coefficient of static friction is .4?
