Physics question (mass at rest raised to height by force. What is velocity)?

AI Thread Summary
To solve the physics problem involving a mass raised to a height by a force, the work-energy theorem is recommended. The equation FΔy = ΔK.E. + ΔG.P.E. can be applied, where G.P.E. is calculated as mgy and K.E. as 1/2 mv². Given the parameters of mass (10 kg), height (12 m), and force (200 N), the relationship between work done and energy changes must be established. Clarification on the problem statement is suggested for better understanding. This approach will lead to determining the velocity of the mass once raised.

m=10k
h=12m
F=200N

Homework Equations


a=v/t
F=ma


The Attempt at a Solution


I cannot find the remaining equations to completely work the problem.
 
Physics news on Phys.org
I recommend using the work energy theorem. For a constant force it will be

F \Delta y = \Delta K.E. + \Delta G.P.E

where G.P.E. is gravitational potential energy and is equal to mgy . And K.E. is kinetic energy and is equal to 1/2 mv^2

(And please try next time to explain the problem a bit more clearly) :wink:
 

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 '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...
