A 200 N box is pushed at a constant velocity up an incline that is 5.00 m long and rises 1.00 m. The incline has a coefficient of kinetic friction of 0.200, and the pushing force is parallel to the incline. The work done by the pushing force is Multiple Choice 475 J. 422 J. 356 J. 300 J. 396 J.
Laika is pushing a box up an incline of 30?. Laika exerts a
force of 20N in the positive x direction (not striaght up the
incline, but into the incline, as shown). Given that the box
started at rest (initial velocity = 0m/s), has a mass of 2kg, and
is accelerating up the incline at a constant rate of 0.5m/s2 for 4
seconds, what is the net Work done on the box? what is the work
done by gravity?
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
You are a member of an alpine rescue team and must get a box of
supplies, with mass 2.10 kg , up an incline of constant slope angle
30.0 ∘ so that it reaches a stranded skier who is a vertical
distance 2.80 m above the bottom of the incline. There is some
friction present; the kinetic coefficient of friction is
6.00×10−2. Since you can't walk up the incline, you give
the box a push that gives it an initial...
20. takes 4.2 s for you to push a box across the floor at constant velocity, a distance of 16 m. What is your power output? The Hk with the floor is 0.45.
You slide a box of books at constant speed up a 30 ∘ ramp, applying a force of 210 N directed up the slope. The coefficient of sliding friction is 0.18. 1.How much work have you done when the box has risen 1 m vertically? 2.What is the mass of the box?
A 350 kg box is pulled 6.40 m up a 30 degree inclined plane by an external force of 5000 N that acts parallel to the frictionless plane. A) Calculate the work done by the external force. Answer in kJ. B) Calculate the work done by gravity. Answer in kJ. C) Calculate the work done by the normal force. Answer in J. Please answer this in a step-by-step fashion, I would like to see the setting up so that I...
A horizontal force of 150 N is used to push a 40-kg box on a rough, horizontal surface through a distance of 6 m. If the box moves at a constant speed, find: a) the work done by the 150 N force b) the work done by friction c) the coefficient of kinetic friction
To push a 26.0 kg crate up a frictionless incline, angled at 25.00 to the horizontal, a worker exerts a force of 214 N, parallel to the incline. Assume that the crate slides 1.50 m. (a) What is the work done on the crate by the worker's applied force? (b) What is the work done by the gravitational force on the crate? (c) What is the work done by the normal force exerted by the incline on the crate? (d)...
You push a box of mass 22.6 kg with your car up to an icy hill slope of irregular shape to a height 4.3 m. The box has a speed 12 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before coming to a rest when hitting a box of mass 89 kg. The heavier box then falls off a sheer cliff...
