Impulse Multiple choice question

AI Thread Summary
In a collision between two unequal masses, the impulse imparted to each mass is equal, despite their different sizes. This is due to the fact that the forces acting between the two objects are equal and occur over the same duration. The discussion clarifies that option C, stating the impulses are equal, is the correct answer. The relationship between force, time, and impulse is emphasized as fundamental to understanding the dynamics of collisions. Overall, the conclusion reinforces the principle of conservation of momentum in such interactions.

Homework Statement


In a collision between two unequal masses, how does the impulse imparted to the smaller mass by the larger mass compare with the impulse imparted to the larger mass by the smaller one?

A) It is smaller.
B) The answer depends on how fast they are moving.
C) They are equal.
D) It is larger.

The Attempt at a Solution


B isn't right.

Impulse is the force multiplied by the time for which that force acts.
In this case, what can you say about the force of object 1 on 2 and object 2 on 1?
What can you say about the time for which these 2 forces act?

In conclusion, what can you say about the 2 impulses?
 
The force is the same and the time in the same; therefore, the impulse on each object is the same.

Perfect :)
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
