Elastic collision physics homework problem

AI Thread Summary
The discussion centers on solving a physics homework problem involving an elastic collision between two cars. Participants are asked to calculate the maximum compression of the car bumpers, given their masses and velocities, along with the spring constant of the bumpers. Key equations mentioned include the energy stored in a spring, E = 0.5 kx^2, and the conservation of momentum for elastic collisions. The conversation highlights the need for clarity on the relevant equations and how to apply them to the problem. Understanding these principles is essential for finding the solution to the homework question.

Hey guys I am completely stuck and have no idea where to start. Help?

Homework Statement



Car A and Car B collide in an elastic collision. Use the data in the table shown to calculate the maximum compression of the car bumpers. The spring constant of the car bumper is 60 000 N/m. Assume that the cars bumpers are of equal length.



Car A
2 500 kg
75 km/h

Car B
3 200kg
-58km/h

1. what are your relevant equations for elastic collisions.
 


it is

E = 0.5 kx^2

it is

E = 0.5 kx^2

that's the equation for energy in a spring.
what are the equations for conservation of momentum: elastic collisions.
 

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...
