Ryan is driving his car to band practice. His speed is 55 mph. Splat! A bug smashes against the windshield, and bug "guts" are e
meriva

Answer:

The answer should be B.

Explanation:

If you punch a wall, no wonder your fist will hurt. The wall adds as much force back into your arm as you did to the wall.

However much force you apply to something, an equal amount of force will come right back at you.

However, in cases like your one, I highly doubt that the bug was flying 55mph. Therefore, since the car has more mass and was traveling faster than the bug, the car has applied more force to the bug than the bug did to it.

Good luck, and I hope that this helps.
