A 25.5 kg block is being pulled by a force F = 241 N up along a rough incline. The coefficient of kinetic friction between the block and the incline is μk = 0.40. The block is pulled through a distance of 27.0 m. Angle is 33 degrees. (a) Solve for the magnitude of the normal force (in Newtons)? -Calculate the work (in Joules) done by the normal force. Pay attention to the angle in the work formula and the...
The object shown has mass m and is pulled by a constant force F directed parallel to the incline. The incline makes an angle 8 with the horizontal. The block moves a distance d up along the inclined plane. The force of friction acts down the incline and has magnitude f. 1. The work done by force F is: a. Fd cos e b.-Fd cos e c.

1.14) A particle of mass m is acted upon by a net force F. As a result of the force, the particle starts from rest and moves along a curved path for which the acceleration relative to an inertial Cartesian coordinate system with an origin at the location where the particle is at rest is given by a - with At, B+Ct, and constants. You may assume that the units associated with t are seconds and = D where A,...

1) A cart for hauling ore out of a gold mine has a mass of 447 kg, including its load. The cart runs along a straight stretch of track that climbs a shallow 4.63∘ incline. A donkey, which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 436 N force for a distance of 115 m by means of a rope that is parallel to the...
