Conservation of Momentum problem.

AI Thread Summary
The problem involves a 50.0g bullet embedded in a 7.00kg stationary block, moving together at a velocity of 5.00m/s. The conservation of momentum principle is applied to find the bullet's initial velocity. After converting the bullet's mass to kilograms, the initial calculations yield an incorrect result of 710m/s. A clarification indicates a minor error in the calculations, leading to the correct answer of 706m/s. The discussion emphasizes the importance of unit conversion and careful calculations in solving momentum problems.

Homework Statement


Im stuck on this question please help. =/
a 50.0g bullet travels right and becomes embedded in a 7.00kg stationary block. the block and embedded bullet moves off at a velocity of 5.00m/s right. what was the initial velocity of the bullet? the answer is 706m/s right.

Watch your units. Try including units when you set up your equation.
 
ohh i see so instead of 50g i convert it to 0.05kg i got 710m/s its still 4m/s off?
 
nvm I am bad sorry for wasting ur time gg it was 35.25 instead of 35
 

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...
