AI Thread Summary
The discussion centers on calculating the distance a block travels before stopping after compressing a spring on a frictional surface. The initial kinetic energy of the block is equated to the final potential energy of the spring and the work done against friction. Participants note that while energy methods are straightforward, using force to determine distance is more complex due to varying acceleration as the spring compresses. An integration of the equations of motion is necessary to account for the changing acceleration. The conversation emphasizes the need for two equations to address the distinct phases of the block's motion.

Moved from a technical forum, so homework template missing.
A block with initial speed 3 meter per second compress the spring in a frictional surface. Given that the spring constant k = 11000 N/M, mass of the block= 2.5 kg, coefficient of kinetic friction= 0.4. Calculate distance d that block travel until it momentarily stopped.

This is my method

initial KE = final PE + Work done by friction

However, is it possible to use force to calculate distance d since the acceleration of block depend on the extent of how much the block compress the spring.

Yes it is. Fill in the proper energy expressions (you do not yet have the right ones in your equation)

[edit] 'perhaps' :rolleyes: you will need two equations for two distinct phases in this exercise

Oh, and: dear lover, :welcome:

Yes, but it won't be nearly as simple as just using energy concepts. Essentially you'll have to integrate an equation of motion where the acceleration is changing with position.
 
Ah... I missed the actual question. So my reply may look somewhat weird :smile:
Thanks, Gneill, for answering that part.
 
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 hanged 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...
