Newtons applied to a constant velocity

AI Thread Summary
To solve for the final velocity of a 1.0 kg object initially moving at 2.0 m/s and acted upon by a 15 N force for 6.0 seconds, Newton's second law is applied to find acceleration. The acceleration can be calculated as a = F/m, which gives a = 15 N / 1.0 kg = 15 m/s². Using the equation V = V0 + at, where V0 is the initial velocity, the final velocity can be determined. Substituting the known values, V = 2.0 m/s + (15 m/s² * 6.0 s) results in a final velocity of 92.0 m/s. This demonstrates the effect of a constant force on an object already in motion.

Homework Statement



A 1.0 kg object, moving with a constant velocity of 2.0 m/s, is acted upon by a force of 15 N in the direction of the motion for 6.0 s. What is the velocity (in meters/second) of the object at the end of this time?


Homework Equations



I was thinking of using, V = Vo + at but at the same time it doesn't make sense to me in finding the solution



help!

You are thinking correctly. You are trying to find V, you know V0, and you know t. You now just need to find 'a' from Newton's 2nd law.
 

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...
