Simple Harmonic Motion and Elasticity

AI Thread Summary
A bullet with a mass of 0.01 kg is fired into a wooden block weighing 2.50 kg, which is attached to a spring with a constant of 845 N/m, causing the spring to compress and the block to oscillate with an amplitude of 0.200 m. The collision is completely inelastic, meaning the bullet becomes embedded in the block. The problem requires determining the bullet's speed before the collision. There is confusion regarding the extra credit question, as it has been changed by the teacher. Participants express a desire for assistance in solving the problem despite the recent change.

Homework Statement


A 0.01 kg bullet is fired horizontally into a 2.50 kg wooden block attached to one end of a massless, horizontal spring (spring constant = 845 N/m). The other end of the spring is fixed in place, and the spring is unstrained initially. The block rests on a horizontal, frictionless surface. The bullet strikes the block perpendicularly and quickly comes to a halt within it. As a result of this completely inelastic collision, the spring is compressed along its axis and causes the block/bullet to oscillate with an amplitude of 0.200 m.
What is the speed of the bullet?

Wow, sorry if you read all that, but I didn't realize the teacher changed the EC question. We aren't doing that one anymore luckily.
 

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...
