AI Thread Summary
A constant net force of 135N is applied to a 30.2kg probe, resulting in an acceleration of 4.47 m/s². Initially, the probe is at rest, and the distance traveled in 6 seconds needs to be calculated. The incorrect assumption was made by multiplying the acceleration by time, leading to an erroneous distance of 26.82m. The correct formula to use is X = Vot + 0.5(a)(t)², which gives a distance of 80.46m after solving. This method accurately accounts for the probe's initial velocity and acceleration over time.

Calculate distance from force HELP!

In outer space, a constant net force of magnitude 135N is exerted on a 30.2kg probe initially at rest. What acceleration does this force produce? How far does the probe travel in 6.00s

what i have so far is that F=Ma
where the force is 135N=30.2a solve for a and get 4.47m/s.

now this is where i get lost. to find the distance I am assuming that it travles 4.47m/s so the gerneal idea i got was to multiply by 6.00s and get 26.82m. This answer is incorrect anyone have any ideas?

ok i got it i figured it out
i had to use a seperat equation where X=Vot + .5(a)(t)^2

x=0(6)+ .5(4.47)(6)^2
solve all that for X and i got 80.46 m and this answer is correct.
 
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...
