If I'm driving at 40 mph and I hit someone going at 40 mph, how much is the force (in mph) they hit with?

Question

I don't know if that actually made any sense, but I think you can get my idea.

Answer 1

well if you hit head on then like they said the force would be net and it would be 80 mph ,but you would have to convert that into newtons using the masses of the cars... if you were behind them ie, chasing them then you and the other person would never collide

Answer 2

mph isnt a force. its speed. needs to be pounds or newtons or something like that

if you both cars weighed exactly the same, the resulting force would be 0.

make it a good day

Answer 3

I'm not sure if you need a mass in solving this problem.

If the car and the person weigh exactly the same, the resultant force is zero.

Answer 4

it would be like crashing at 80 mph

Answer 5

If you are travelling toward each other, then you are each being hit at 80 mph.  If you are travelling in the same direction, then there is no force at all (in theory)

Answer 6

Newton's second law states:

Force = mass x acceleration.

If the speed of 40 mph is constant, then, acceleration=0 mph/hr

Hence Force=0 newton.

By the way, force is not expressed in mph.

Answer 7

1) Force is not measured in mph.

2) You have to define the velocity vectors and duration of impact.

Your question is at best, incomplete,and at worst nonsense.
