Two pop cans are at rest on a stand. a firecracker is placed between the cans and lit. the firecracker explodes and exerts equal and opposite forces on the two cans. assuming the system of two cans to be isolated, the post-explosion momentum of the system
a. is dependent upon the mass and velocities of the two cans
b. is dependent upon the velocities of the two cans (but not their mass)
c. is typically a very large value
d. can be a positive, negative or zero value
e. is definitely zero

e. is definitely zero

Explanation:

Given that

At initial condition the speed of the pop cans is zero.

We know that linear momentum

P = Mass x velocity

P =  m v

At initial condition v = 0

P= 0

If there is no any external force then the linear momentum of the system will be conserve.And given that ,consider the system isolated.

Therefore the answer is e.

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
