Given position and velocity, find acceleration

AI Thread Summary
To find the acceleration of an airplane that accelerates uniformly from rest over 800 feet to a speed of 100 ft/sec, the relevant equations of motion must be applied. The relationship between acceleration, velocity, and time can be expressed in differential form, utilizing the Chain Rule to incorporate displacement. The solution involves integrating these relationships to derive the acceleration. The key is to recognize that velocity is the derivative of position with respect to time, while acceleration is the derivative of velocity. Proper application of calculus principles will lead to the correct determination of acceleration.

Homework Statement



An airplane has a constant acceleration while moving down the runway from rest.
What is the acceleration of the plane if it requires 800 ft. of runway before lifting o
at 100 ft./sec.?

You have to post your attempt. Start with the equation of motion that's most relevant here.
 
sorry, wrong section its for a calculus class and we have to solve by integration and I am not sure where to start.

OK, then, start by writing down the relationship between acceleration, velocity and time in differential form.

Then apply Chain Rule to bring displacement into there somewhere. There's more to do, but why don't you start with this?
 
You are expected to know that velocity is the derivative of position with respect to time and acceleration is the derivative of velocity.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
