A cart loaded with bricks has a total mass of 22.1 kg and is pulled at constant speed by a rope. The rope is inclined at 30.1 ◦ above the horizontal and the cart moves 23.9 m on a horizontal floor. The coefficient of kinetic friction between ground and cart is 0.3 . The acceleration of gravity is 9.8 m/s2 . What is the normal force exerted on the cart by the floor? Answer in units of N. b) How...

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...

A box of mass ?=22.5 kg is pulled up a ramp that is inclined at an angle ?=17.0∘angle with respect to the horizontal. The coefficient of kinetic friction between the box and the ramp is ?k=0.305 , and the rope pulling the box is parallel to the ramp. If the box accelerates up the ramp at a rate of ?=2.49 m/s2, calculate the tension ?T in the rope. Use ?=9.81 m/s2 for the acceleration due to gravity. FT=_____N

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...
