    Conceptual Force
AI Thread Summary
An object initially at rest accelerates to speed v after a force F acts on it for time T, following Newton's second law (F=ma). When the object's mass is doubled and the force is quadrupled, the new force acting on the object is 4F, while the mass is now 2m. The acceleration can be calculated using the modified equation, resulting in a new acceleration of 2a. To find the time required to reach speed v with the new parameters, it can be determined that it takes T/2 for the object to accelerate from rest to speed v. Understanding impulse and the relationship between force, mass, and acceleration is crucial in solving this problem.

Homework Statement


An object of mass m is initially at rest. After a force of magnitude F acts on it for a time T, the object has a speed v. Suppose the mass of the object is doubled, and the magnitude of the force acting on it is quadrupled.
In terms of T, how long does it take for the object to accelerate from rest to a speed v now?

Hello,

spend some time to concept of Impulse ;]
 
just use NEWTON'S SECOND LAW OF MOTION
 

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...
