    Horsepower Work
AI Thread Summary
The discussion revolves around calculating how high an electric motor can lift a crate based on its horsepower output. The motor's output is converted from ferretpower to horsepower, resulting in 8,580 hp, which is then converted to watts. The weight of the crate is determined to be 40.1 kg, leading to a calculation of work done in lifting the crate. The final height calculated is 81,405 meters. The accuracy of the motor's horsepower and the validity of the teacher's numbers are questioned, indicating potential discrepancies in the problem setup.

Homework Statement


If one ferretpower (fp, made-up unit) is equal to 0.0312 hp, and an electric motor puts out 2.75 x 10^5 fp, how high (in meters) can it lift a crate that has a mass of 2.75 slugs in 5 s?

Homework Equations


P = W/t W = mgh
1 hp = 745.7 watts
1 slug = 14.59 kg

The Attempt at a Solution


Converted fp to hp to get 8,580 hp. Converted hp to watts to get 6,398,106 watts. Found weight of crate to be 40.1 kg. Used W = Pt to get 31,990,530 J. Used W/mg = h to get my final answer of 81,405 m. Is this the same answer you got?

what is your question? Your process looks correct but do you really have a 8580 hp motor?
 
My teacher's numbers tend to be quite stupid. Thanks for the reply.
 

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...
