250N is 56.2 pounds at Earth's surface.
It depends on the output force and input force and what the levers look like. For example: if you can use a type one lever to lift 500 N with 100N, the adv would be 5. But, if you can only lift the 500N with 250N, then the adv is 2.
250N
40:250::n:100% 250n = 4000% n = 16%
250N Latitude passes just south of Brownsville TX in Mexico,) and through south Florida slightly north of Key West.
And the question is????
The force of gravity on the moon is approximately one sixth that of the earth. The direct variation formula for weight on the earth compared to weight on the moon would be weight on earth divided by 6 is equals to weight on the moon.
Solving the car first: Using F=ma Assuming a linear deceleration, the car goes from 5m/s to 0m/s in 2 seconds. That is 2.5m/s^2 which is the acceleration. F=100*2.5 F=250N (100kg is very light for a car. A normal small car will weigh 1000kG and trucks will weigh usually between 5 to 50tonnes but can be over 1100 depending on the legal limit on the number of trailers a prime mover can tow) The truck will be 25kN
This is hard to calculate precisely, due to the fact that Earth's density increases towards the center. However, you make a simplified calculation, by assuming a uniform density. Just calculate the ratio of the volume (and therefore, of mass) of a sphere which has half the radius of the Earth, and calculate the gravitational attraction (once again, you only need a ratio, compared to the complete Earth) on that object.
