Calculate Change in Momentum of 20kg Box

AI Thread Summary
To calculate the change in momentum of a 20kg box initially traveling at 10m/s when pushed with a force of 48N for 12 seconds, first determine the initial momentum, which is 200 kg·m/s. The force applied will cause an acceleration, calculated using Newton's second law (F=ma), resulting in a change in velocity. After finding the new velocity, the final momentum can be calculated, and the change in momentum is the difference between the final and initial momentum. The discussion emphasizes the importance of understanding the relationship between force, mass, and acceleration in momentum calculations.

1. A 20kg box traveling at 10m/s is pushed with 48N of force for 12 seconds. What is the change in momentum?



3. How would you find the change with this?

* I know the momentum of the ball initially is 200.

So you get the momentum by multiplying velocity with mass. What will be the velocity of the box if it is pushed with 48 N for 12 seconds?

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
