How can you calculate the maximum distance of a mousetrap car without knowing force or acceleration?

First off, A mouse trap lever only moves 180 degrees.
So you would take the length of your mouse trap pulling arm (e.g. 12''), and multiply it by two (24'')
Now you have the diameter of the circle if the mousetrap arm could spin a full 360 degrees.
So to find the circumference of that invisible circle you would multiply the diameter by pi (24'' x 3.14 = 75.36'') Now since the mouse trap arm only moves 180 degrees, you would divide your answer by 2, because 180 is half of 360.
(75.36'' divided by 2 = 37.68'')
Now that you have the distance that the arm travels you need to find the circumference of the axle your pulling wheels are on. Say that your axel has a quarter inch diameter ( .25'' ) you would do the same thing as before:
(e.g. .25'' x pi [3.14] = 0.785'')
Now you would divide the distance your lever arm moves by the circumference of your axle (e.g. 37.68'' divided by 0.785'' = 48)
this means that the string tied to the tip of the arm would wrap around the axle 48 times.
Now for the final step the circumference of the wheels, just do the same as before, diameter multiplexed by pi.
(e.g 5'' x 3.14 = 15.7'' )
Now that you know how many times the axle will rotate (48 times) and how far it travels each rotation (15.7'') all you have to do is multiply them!
e.g. (48 x 15.7 = 753.6'' )
or 20.93 yards, one fifth of a football field!
But keep in mind this is in a world with out friction.
I apologize if I was at all confusing, im not too good at teaching things, haha.
I hope I helped!

How do you calculate a coefficient knowing the expected rate of return and standard deviation?
It depends on what the underlying distribution is and which coefficient you want to calculate.
How do you determine distances on earth mathematically knowing the coordinates?
By using the distance formula. We calculate the difference of the like coordinates (e.g longitude1-longitude2 or latitude1-latitude2 etc) then add the "squares" of the differences. And finally taking the square root of the answer.
How do you calculate volume if given bulk density?
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
How do you calculate the radius of a turn based on a path or curve without knowing the circumference or diameter?
You cannot.
How do you calculate the average speed without knowing the speed only the time?
To calculate the average speed of /anything/ you need to know the distance it traveled (IE: 500 meters) and the time it took to travel that (IE:50 seconds) Here's how to calculate it: You take the total distance and divide it by the time. So in our example, a car traveled 500 meters in 50 seconds, so the speed would be: 500 meters / 50 seconds = 500/50 = 10 meters / second. So the car would be traveling 10 meters per second.

How many hrs is 25kms?
Speed is distance over time. Without knowing the speed, we cannot calculate this.
How can you find the weight of of humans on other planets?
1). As an artificial space vehicle approaches and passes another planet, we can observe the effect of the other planet on its motion. 2). Knowing the vehicle's mass, and the effect the other planet has on its motion, we can calculate the other planet's mass. 3). Knowing the time the other planet takes to revolve around the sun, we can calculate its distance from the sun. 4). Knowing the other planet's distance from the sun, and its apparent size as seen from earth, we can calculate its actual size. 5). Knowing the other planet's actual size and mass, we can calculate the gravitational field at its surface, or at any distance from its center. 6). Knowing the gravitational field at any distance from the center of the other planet, we can calculate the weight that any familiar object would have if it were on or near that planet.
How do I find the free-fall acceleration only knowing the variables of distance and initial speed?
To find free-fall acceleration using only distance and initial speed, you can use the kinematic equation: distance = (1/2) * acceleration * time^2. Since the initial speed affects the time of fall, you would need to know the time of fall or other variables in order to solve for acceleration with just distance and initial speed.
How does newton's second law apply to jai alai?
Any time an object moves, and especially if it changes its velocity, the laws of motion apply. For example, you can use it to calculate the desired force, if you know the acceleration and the mass. Or the other way - to calculate the acceleration, knowing the force and the mass.
How long does it take to 5 miles?
Speed is distance over time. Without knowing the speed, we cannot calculate this
How many minutes are in a kilometer?
Speed is distance over time. Without knowing the speed, we cannot calculate this.there is no conversion from minutes (time) to kilometres (distance)
How do you calculate a planet's mass when given orbital speed and distance from sun?
You can use the formula M = (V^2 * R) / G, where M is the planet's mass, V is the orbital speed, R is the distance from the sun, and G is the gravitational constant. By plugging in the values of V and R, you can calculate the planet's mass.
How can you calculate acceleration of gravity with Atwood Machine?
The acceleration of gravity can be calculated using an Atwood machine by measuring the acceleration of the system as the masses move and applying Newton's second law of motion. By knowing the masses of the objects and the tension in the rope, one can determine the acceleration due to gravity.
How long does it take to travel 18 miles?
Speed is distance over time. Without knowing the speed, we cannot calculate this.
How do you find the individual force?
To find the individual force acting on an object, you can use Newton's second law, which states that force is equal to mass multiplied by acceleration (F = ma). By knowing the mass of the object and its acceleration, you can calculate the individual force.
How to calculate x of a lens knowing only the focal length which is the distance from the lens to the image of sun formed by it correct me if I'm wrong?
1/(focal length) = 1/(distance of object) + 1/(distance of image) is the formula for calculating x of a lens knowing only the focal length which is the distance from the lens to the image of sun formed by it.
What is the magnification of a lens with a focal of 2 in?
The magnification of a lens depends on the object distance and image distance from the lens. The magnification formula is given by M = -image distance/object distance. Without knowing the object distance, it is not possible to calculate the magnification of the lens with a focal length of 2 inches.
