A block of mass m= 15 kg is pulled along a flat surface with a horizontal force F = 135 N. The force of kinetic friction between the mass and the surface is fk = 30 N. What is the acceleration of the block? 9.0 m/s2 7.0 m/s2 4.5 m/s2 2.0 m/s2
A block of mass M is pulled over a rough horizontal surface. The block has a coefficient of kinetic friction with the surface of . The block is subject to the normal force, the friction force, the force of gravity, and a force from a rope of magnitude T which pulls up and to the right at an angle of 0 with the horizontal. The box was initially travelling to the right at speed v = 2.7 m. If M...
Problem 1: A wood block is slid back and forth against a flat surface covered with sandpaper. The nominal contact area between the block and the paper is a rectangle with sides 0.03 m and 0.06 m in length. The block is slid back and forth 100 times. The hardness of the block is 5 MPa. This motion causes a 1.3 mm layer of material to be removed from the block's sliding surface. Use the diagram below for additional information....

Please help A. A block is pulled along a horizontal surface by a force of 12.0 N. The block has a mass of 4.00 kg and it accelerates at 2.00 m/s. Find the coefficient of kinetic friction for the interface between the block and the surface. B. A stone falls vertically through the air and experiences a drag force. If the stone's mass is 6.00 kg. and the drag force (upwards force) is 14.0 N, what is the acceleration of...
Problem 1: (4 points) A block of mass m = 22.5 kg is being pulled at constant speed by a rope. The rope is inclined at θ = 20.00 above the horizontal, and the cart moves a distance d-20.0m on a horizontal rough surface. The coefficient of kinetic friction between the ground and cart is μ-0.5. a) what is the tension in the rope? b) How much work is done on the cart by the rope? How much work is...

A mass m = 14 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.12, for a distance d = 5.9 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 38° with the horizontal. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 38° (thus on the incline it is...
