Two boxes connected by a light horizontal rope are on a horizontal surface, as shown in the following figure. The coefficient of kinetic friction between each box and the surface is 0.30. One box (box B) has mass 4.84 kg , and the other box (box A) has mass m . A force F with magnitude 37.3 N and direction 53.1 ∘ above the horizontal is applied to the 4.84 kg box, and both boxes move to the right with...
4) Bubba pulls two boxes across the floor of his barn. One box has a mass (m1) of 20.4 kg and has a coefficient of kinetic friction of 0.321 with respect to the floor. The second box has a mass (m2) of 23.1 kg and a coefficient of kinetic friction of 0.177 with respect to the floor. The two boxes are connected with a rope. Bubba pulls on another rope connected to the second box. All of the ropes are...
The UPS guy is delivering two rectangular boxes to the 4th floor. The boxes are stacked vertically in the elevator. The one on the bottom has a mass of 5.00 kg and the one on the top has a mass of 2.00 kg. The elevator, the UPS guy, and both boxes are accelerating upward at 2.50 m/s2. What is the magnitude of the normal force between the two boxes? For the physical representation (part 2a), draw and label an appropriate...
two boxes are connected by a rope. mass of box 1 is 10kg and box 2 is 30kg. the coeff of kinetic friction boxes and ground is 0.1. a person is pulling box 2 with 80N right. a. find nagnitude if the friction force on box 1 and box 2. b. find the acceleration of the boxes c. find the tension in the rooe connecting the boxes
The 10.0 kg box shown above is sliding to the right along the floor. The coefficient of kinetic friction between the box and the floor is 0.20. What external force would be required to move the box at a constant velocity?
1. Two boxes are stacked on a frictionless table. M. = 4kg and M, 5kg. The coefficient of friction between the boxes is such that when a 27 N force F is applied to the lower box, the boxes start to slip relative to each other. The system is then restored to rest and force F is removed. A horizontal force F is now applied to the upper box. What is this force's maximum value in order for the two...
5) A box of mass 25 kg is dragged across a level floor by a rope that makes an angle of 25o above the horizontal. The coefficient of friction between the box and the floor is 0.72. Find the force F that will ensure the box moves with constant speed.
1) Consider two boxes: box B, with a mass of 3kg, placed on top box A, with a mass of 10kg. If box A is pushed with a force of 70N, what is the force of friction on box B? The coefficients of friction between boxes A and B are µs = 0.7 and µk = 0.4, while friction is negligible between box A and the ground. 2) A 1.5kg box is pushed up a 30o incline with a force...
Three boxes, with masses m1, m2, m3 (kg) are stacked vertically; the bottom box is in contact with a rough floor and the surfaces between each box are also rough. An external force Fext (N) acts on the bottom box at an angle of XX degrees relative to the horizontal, as a result of which all three masses accelerate together with an acceleration a (m/s^2). a) Identify the number of forces acting on each box, b) starting with the top...
3) Two boxes sit on a horizontal table. Box 1 (m1 = 13 kg) is attached to box 2 (m2 = 34 kg) by a rope. You pull on a rope attached to box 2 with a force of 55 N. The coefficient of kinetic friction between both boxes and the table is 0.11 . (a) What is the acceleration of the boxes? (b) How far will the boxes move in 6.0 seconds? Assume they start from rest.
