How do I find velocity from acceleration?

AI Thread Summary
To find velocity from acceleration, one must consider the initial conditions and the equations of motion. In this scenario, an automobile and a truck start from rest with different constant accelerations, leading to the automobile overtaking the truck after the truck has traveled 41.0 meters. The equation r = r + Vt + 1/2at^2 is relevant for calculating distance based on time and acceleration. A user attempts to solve for velocity but encounters an error in their calculations, prompting a request for a detailed breakdown of their work to identify the mistake. Accurate application of kinematic equations is essential for solving such problems effectively.

How do I find velocity from acceleration??

1. An automobile and a truck start from rest at the same instant, with the automobile initially at some distance behind the truck. The truck has a constant acceleration of 2.00 , and the automobile an acceleration of 3.42 . The automobile overtakes the truck after the truck has moved a distance 41.0 .



r=r+Vt+1/2at^2



I get 40=vf^2/4, which gives me 40, but that's not right.

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'

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...
