Can a 1% grade hill make 1mph on a 3,500 ton truck.ok so 1% grade is 1 ft of elevation every 100 yard so 1/100 .01% = 1%
But I want to do this in 3 yards ! (Can 1 ft still be used in 3 yards?)


(IMPORTANT)
IN OTHER WORDS I WANT TO MAKE THE SCENARIO OF A 3,500 truck going at 35 mph goes down a 1% grade and suddenly in 3 yards gains a mile in 1.47 seconds it requires a vehicle to gain a mph.THIS IS THE STORY.!


REMEMBER THIS TRUCK IS GOING 35mph I want to prove another 1 mph making the truck go 36mph is the result of this 1 % grade.


1mph takes 1.47 seconds how the **** can I prove a 3,500 ton truck GOING 35mph on a 1% grade hill in 3 yards will accumulate the 1 mph


We got TIME ,WEIGHT OF OBJECT,SPEED,ANGLE,


IF YOU GET THIS YOU ARE AMAZING!

It would also be a violation of the forum policy. Sorry. For further info, kindly please re-read the "Read Before Posting" announcement.

Can a 1% grade hill make 1mph on a 3,500 ton truck?
I'm sorry, but you're going to need to explain your terms. What do you mean by "making" a speed "on" a vehicle? Are you asking if a surface with a given grade might be able to overcome rolling friction and, with the gravity assist of the slope, be able to cause a given vehicle to begin moving and then reach a target speed? If so, there is so much information missing that the question is probably completely unanswerable. If not, what do you mean?

ok so 1% grade is 1 ft of elevation every 100 yard so 1/100 .01% = 1%
No, it isn't. (here or here, for example.)

If the surface goes up one foot for every three hundred feet, this is:

. . . . .\(\displaystyle \dfrac{1}{300}\, =\, 0.00333...\, =\, 0.333...%\, =\, \dfrac{1}{3}%\)

...not one percent.

But I want to do this in 3 yards !
You want to do what in three yards?

(Can 1 ft still be used in 3 yards?)
No, but one can use three feet in one yard.

What do you mean by "making a scenario"? Are you needing to figure out what the rolling resistance (or something) is, in order to make this scenario occur? If so, what other information are you given? What are you supposed to assume? If not, what are you talking about?

In either case, what are all the rolling specs of the truck? (efficiency, momentum v. velocity v. acceleration, tires, etc) What are all the specs of the roadway? (surface type, surface condition, humidity, etc)

When you reply, please provide all of the modelling assumptions that you're expected to use for this exercise, such as every formula, constant, variable (plus definition). Include a clear listing of all of your thoughts and efforts so far, so we can see where things are bogging down. Thank you! ;)

(By the way, this sort of physics exercise is helpful in explaining by "accident reconstruction" is an inexact process, and why the professionals who provide this service can charge so much!)
