In a collision between two objects having unequal masses, how does magnitude of the impulse imparted to the lighter object by the heavier one compare with the magnitude of the impulse imparted to the heavier object by the lighter one?

a. the lighter object receives a larger impulse

b. the heavier object receives a larger impulse

c. both objects receive the same impulse

d. the answer depends on the ratio of the masses

e. the answer depends on the ratio of the speeds

Explanation:

The impulse has as an expression

      I = ∫ F dt

In addition, on impulse of isolated systems is

       I =ΔP = m vf - m v₀

Let's replace

      F dt = m (vf -vo)

The force in these shocks laqueunxcyerpoesjerce on the other, using the law of action and reaction state forces has the same magnitude and the time of the shock is equal for the two bodies, this implies that the impulse is equal for the two bodies

Let's check the answers

a) False as the forces are of action and reaction the impulse must be equal

b) False

c) True. Why do we have an action and reaction stop

d False

e) false

explanation:

v=uf/(u-f)
