AI Thread Summary
A 2.0 kg frictionless cart initially moving at 3.0 m/s to the right collides with a stationary mass and ends up with a speed of 1.6 m/s. The discussion seeks to calculate the velocity and mass of the second cart post-collision. Participants are clarifying which final velocity is relevant to the calculations. The problem requires applying principles of conservation of momentum to find the unknowns. Understanding the equations and concepts involved is crucial for solving the homework problem effectively.

Homework Statement


hey everybody i got a problem but do not know how to do it, A 2.0 kg frictionless cart is moving at a constant speed of 3.0m/s to the right on a horizontal surface. it then collides with a mass that is at rest. as a result the cart acquires a speed of 1.6m/s. Neglect friction.

Caluclate magnitude and direction of the velocity of the 2.0 kg cart after the collison
Calculate mass of the second cart.


Homework Equations


Im not sure what equations i need to use so that's why i am here.


The Attempt at a Solution


No idea of how to solve please help thanks alot.

Hi Fabio, welcome to PF.

Which final velocity is given? Cart or mass?
 

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...
