The box acquires (75 x 2.5) = 187.5 joules of gravitational potential energy.
The efficiency of your effort is (187.5 / 425) = 44.1% (rounded)

What is the mechanical advantage of a ramp if you and two friends apply a force of 425 N to push a piano up a 2.0m long ramp?
-- angle the ramp makes with the ground -- weight of the piano -- height above ground at the top of the ramp -- horizontal distance between the beginning and end of the ramp If the question included any one of these pieces of information, an answer could be calculated. But with only the information given, it can't be.
A constant push of 250 N is needed to slide a crate that weighs 400 N along a 2 meter long ramp If the ramp raises the crate 1 meter what is the ramp's efficiency?
80%
What is the mechanical adventage of a ramp that is 20 feet and 2 feet above ground?
The theoretical mechanical advantage is the length of the ramp divided by its height. 20/2=10.
Name all the factors that affect the distance taken for a toy car to stop after rolling down a ramp?
- The slope and length of the ramp. - The rolling friction between the tires and the ramp/ground. - The air resistance (which is dependent on the velocity and geometrical shape of the car). - The direction and speed of the wind. - The smoothness of the ground (a rugged surface will slow the car down).
What is an example of inclined plane?
You help a buddy move, and he rents a moving truck. To load or unload the truck, you take the ramp out, attach it to the rear of the truck and let it slope to the ground. The ramp is an inclined plane.
How do you drop a ramp on Skate 3?
Stand above a ramp and push triangle.

Does increaseing the length of a ramp increases the efficiency of the ramp?
Increasing the length of a ramp may increase its efficiency by reducing the steepness of the incline, making it easier to move objects up or down the ramp. A longer ramp provides a gentler slope, requiring less force to overcome gravity.
How steep to make a wheelchair ramp when door is 2 meters above ground and 15 meters from garage?
7.5 degrees
How would you use the word ramp in a sentence?
Push the cart up the ramp, please.
How do you find efficiency of a ramp?
To find the efficiency of a ramp, you would calculate the output work (weight lifted) divided by the input work (force applied). The formula for efficiency is (Output Work/Input Work) x 100%. A more efficient ramp would require less input work to lift a certain weight.
How do you increase the efficiency of pushing a concrete block up a wooden ramp?
Reduce the friction of it and the ramp, for example, mounting it on wheels.
What is the effort needed to push a 75 pound weight up the ramp?
The amount of effort needed to push a 75-pound weight up a ramp depends on the angle of the ramp, the friction present, and whether any external forces are acting on the weight. Generally, the steeper the ramp, the more effort is required to push the weight up. It can be calculated using the equation: force = weight * sin(angle of the ramp).
If a ramp were coated with a smoother surface the ramp and efficiency would?
The smoother the surface of a ramp, the greater is the danger of a vehicle slipping and losing traction.A wet, smooth ramp could cause a pedestrian to slip over and be hurt.
With how much force does a ramp push a ball rolling down it?
A ramp exerts no force, just gravity.
