Allison is pushing a box to the right on a horizontal floor. The magnitude of the force of friction between the box and the floor is 40N. Allison pulls up and to the right with a force of 150N at an angle of 35 degrees to the floor. The box slides to the right at 3m/s^2 without moving up or down. (The x axis is horizontal and positive toward tht right. The y axis is vertical and positive is upward) A. F applied in component form? B. Force of friction in component form? C. Net Force in component form (with an unknown)? D. Now using Newtons 2nd law of motion for x direction we find? E. The weight of the box?

Rachel is pushing a box across the floor while Jon, at the same time, is hoping to stop the box by pushing in the opposite direction. There is friction between the box and floor but you may ignore the effect of air resistance. Draw the force diagram for the box's motion and then choose the appropriate forces from the following list that should be included on the force diagram. Assume that the box is moving to the right during the...

A chimpanzee named Allison pushes a box. She loads the box full of her toys until it has a mass of 8 kg. The coefficient of kinetic friction between the box and the floor is mu k = 0.4. The box is initially in motion, and moving at a velocity of 1.2 m/s to the right. a) If Allison pushes horizontally to the right with a force of 60N, what is the acceleration of the box? Is the box speeding...

A 30-kg box is at rest on a horizontal floor with friction coefficientsμs= 0.65 (static) and μk= 0.55 (kinetic). You push on the box HORIZONTALLY (parallel to the floor) with varying applied force. For each applied force below, find the magnitude of the friction force exerted by the floor on the box(in Newtons), and state whether the friction is static or kinetic. (a) Applied force 100 N. (b) Applied force 150 N. (c) Applied force 190 N. (d) Applied force...

While moving in, a new homeowner is pushing a box across the floor at a constant velocity. The coefficient of kinetic friction between the box and the floor is 0.423. The pushing force is directed downward at an angle θ below the horizontal. When θ is greater than a certain value, it is not possible to move the box, no matter how large the pushing force is. Find that value of θ.

a student pulls a box of books on a horizontal floor with a force of 100 N in a direction of 37.0 degrees above the horizontal. if the mass of the box and the books is 40.0 kg and the coefficient of static friction between the crate and the dock is 0.55, what is the maximum force of friction? (Will the box move?) Show the free body diagram. (183, 167, 332 or 350 N)

A person pulls on a 8.7 kg crate as it slides across a level floor using a rope attached to the center of the crate. The floor has a non-zero coefficient of kinetic friction. The crate began with a speed of 1.4 m/s and speeded up to 2.4 m/s while being pulled a horizontal distance of 2.0 meters. If the force exerted by the rope is 20 Newtons, and the rope pulls completely horizontally, what is the work in J...

A person pulls on a 9.4 kg crate as it slides across a level floor using a rope attached to the center of the crate. The floor has a non-zero coefficient of kinetic friction. The crate began with a speed of 1.9 m/s and speeded up to 2.8 m/s while being pulled a horizontal distance of 2.0 meters. If the force exerted by the rope is 20 Newtons, and the rope pulls completely horizontally, what is the work in J...

A small box is held in place against a rough vertical wall by someone pushing on it with a force directed upward at 28 degree above the horizontal. The coefficients of static and kinetic friction between the box and wall are 0.40 and 0.30, respectively. The box slides down unless the applied force has magnitude 23 N. What is the mass of the box?
