A 15.0 kg box is being pulled across a rough floor at a constant acceleration of 3.00 m/s^2 by means of a rope. The rope makes an angle of 34.0 degrees above the horizontal. The coefficient of kinetic friction between the floor and the box is u=0.250. Calculate the magnitude of the tension in the rope?
Problem 2 Two blocks (of masses m and m,) are connected by a massless string, as shown below. They are pulled up an incline of angle θ by a constant force applied to m2, which we'll call F., for convenience. (Note that, is the tension in the rope held by the woman and is directed parallel to the incline.) There is no friction between m, and the incline, but there is kinetic friction (of coefficient ) between m, and the...
A) A massless rope is tied to a 1.82 kg box sitting on a rough, horizontal surface. The rope is pulled with constant force F acting upward at an angle 15.8o to the horizontal. The coefficient of kinetic friction between the box and the surface is 0.217, and the box slides at constant speed along the table for a distance of 84.4 m. Find the total work done by F, in J. B)Josh, mass 143 kg, is racing against his...
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...
Can you answer questions 2,3 4 and 5.Thank you so much for your help Question 2 ng and 5x is at A 15 kg box initially at rest is released makes an angle of 40° to the horizontal. The box is attached to a ball of mass 15496 is released from the top of an incline plane that is 7 m long and e horizontal. A 60 N friction force impedes the motion of the box to a ball of...
Question 13 13 pts A box of mass 0.8 kg is being pulled up a slope that is inclined by 60° compared to the horizontal. The tension in the rope pulling the box is 40 N and the rope is parallel to the incline. The slope is NOT frictionless and the coefficient of kinetic friction between the box and the slope is 0.35. Round off your answers to two decimal places. (a) What is the magnitude of the weight of...
2. A block of mass 15.0 kg is being pulled up a flat incline of angle 30.0? and coefficient of kinetic friction 0.120 by a string. The tension in the string is 120 N, and is directed parallel to the incline, as shown in the diagram below. (a) What is the value of the force exerted on the block by the incline? (That is, what is the block�s apparent weight?) (b) What is the magnitude of the block�s acceleration? 2....
Just need help on the red X A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 79.8 N at an angle of 28.0° above the horizontal. The box has a mass of 20.0 kg, and the coefficient of kinetic friction between box and floor is 0.300. (Indicate the direction with the sign of your answer.) (a) Find the acceleration of the...

A block of mass M is pulled over a rough horizontal surface. The block has a coefficient of kinetic friction with the surface of u. 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. If M 9.4kg, u=0.27, T-42N, and 0=38.6 degrees, what the work done by the rope on...
