Comparing Impulse in Collisions: Which Ball Experiences a Greater Magnitude?

AI Thread Summary
In the discussion about the impulse experienced by two equal mass balls dropped from the same height, participants analyze the scenario where the red ball rebounds higher than the blue ball. The key point is that impulse is defined as the change in momentum, and since both balls have equal mass and are dropped from the same height, they experience the same magnitude of impulse during their collisions with the floor. Some participants express uncertainty about the answer, with one suggesting that the impulse cannot be determined without knowing the time intervals and forces involved. Ultimately, the consensus leans towards the idea that both balls experience the same magnitude of impulse, highlighting the conservation of momentum in this context. The discussion emphasizes the relationship between impulse and momentum in collision scenarios.

Homework Statement


2 equal mass balls (one red one blue) are dropped from the same height and rebound off the floor. the red ball rebounds to a higher position. which ball is subjected to the greater magnitude of impulse during its collision with the floor?

a. it's impossible to tell since time intervals and forces are unknown.
b. both balls were subjected to the same3 magnitude impulse.
c. blue
d. red


Homework Equations



impulse = f*deltat

The Attempt at a Solution



i think the answer is b, but I'm not sure

kallisti, welcome to PF! What's the equation that relates impulse to momentum?
 
impulse equals change in momentum.

so are they the same, since momentum is conserved?
 

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
