a 15 kg box sits on an 12^o incline with a mu = 0.75. find the work done to push the box uphill 5m at a constant velocity
A box (mass 25.8 kg) sits on a rough incline that makes an angle α = 28.1o with the horizontal. A massless string is tied to the box, runs parallel to the incline, passes over a massless, frictionless pulley, and is tied to mass M hanging on the other end. Assume μs = 0.455 is the coefficient of static friction between the box and the surface of the plane. Find the maximum value of M, in kg, for which this...
Jim pushes a 15 kg box up along a 42 degree incline by applying a force parallel to the incline. If the coefficent of friction between the incline and the box is 0.34, what force must he apply to move the box at constant velocity?
A 4 kg box sits on a ramp where the coefficient of friction is 0.2. Find the angle that will cause the box to slide downhill at constant velocity.
A 2 kg box sits on a ramp of 5 degrees where the coefficient of friction is 0.2. A 31 N force pulls the box uphill. Find the acceleration.
A 4 kg box sits on a ramp of 7 degrees where the coefficient of friction is 0.2. A 34 N force pulls the box uphill. Find the acceleration.
How far can you push a 30 kg box at a constant velocity up a 20º incline if 6 kJ of work is done? 20 m 22 m 25 m 30 m
A 61 kg box sits at the bottom of a ramp inclined at 35*; the rough surface of the incline has a coefficient of kinetic friction at 0.24. When given a push of 87 N, the box begins moving with an initial speed of 5.6 m/s. Eventually, the box comes to rest. How high above the bottom of the ramp will the box be when it stops moving?
A 5.00 kg box sits on a ramp that is inclined at 37.3 ∘ above the horizontal. The coefficient of kinetic friction between the box and the ramp is 0.27. What horizontal force is required to move the box up the incline with a constant acceleration of 4.30 m/s2 ?
A 5.0 kg box is on an incline tilted 45° from the horizontal. The coefficient of static friction between the box and the incline is 0.62. (a) Find the smallest force you have to push with (up along the incline) to keep the box from sliding down the incline. (b) Find the largest force you can push with before the box starts sliding UP the incline. Draw separate free-body diagrams for the two cases, and think carefully about which way...
A box of mass 11.0 kg is on an incline at an angle of 0 = 12 degrees. It is being pulled at a constant speed by a rope at an angle of Q=15 degrees (relative to the incline). The rope is has a tension of 25 N. What is the coefficient of kinetic friction uz?
