    Box Force Lift
AI Thread Summary
To calculate the force required to lift a 2000N box with an acceleration of 8 m/s^2, one must consider both the weight of the box and the additional force needed for acceleration. The net force acting on the box during the lift can be determined using Newton's second law, F_net = ma. The total force required is the sum of the gravitational force and the force needed for acceleration, resulting in an applied force of 3,630N. Understanding the relationship between mass, acceleration, and net force is crucial for solving this problem. This calculation illustrates the application of fundamental physics principles in real-world scenarios.

A box weighs 2000N and is accelerated uniformly over a horizontal surface at a rate of 8 m/s^2. The opposing force of friction between the box and the surface is 27.4 ..

How much force would be required to lift the box upward with an acceleration of 8 m/s^2?

I know that the answer is 3,630N .. but I'm not sure how to get there?
 
Physics news on Phys.org
Some of the information in the question doesn't relate to the problem, but anyways, this is an application of F_{net}=ma. You know mass and acceleration, now what is the net force acting on the object while it is moved upward? Develop the equation and solve for applied force.

What forces act on the box when you lift it? Set the net force equal to ma (Newton's 2nd law).
 
Ok got it =D thankyou
 

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...
