Titan by Mack™: Extreme Truck for an Extreme Job

Question on momentum: If a Mack truck and a Volkswagen traveling at equal speeds have a head-on collision...?

If a Mack truck and a Volkswagen traveling at equal speeds have a head-on collision, which vehicle will experience the greatest force of impact? The greatest change in its momentum? The greatest acceleration? Would the force of impact be equal on both vehicles, due to Newton's 3rd law of motion? Also, I'm not sure of the greatest change in momentum or acceleration. I believe it is the Volkswagen due to its smaller mass but I'm not sure. Any help would be greatly appreciated. Thank you!

i made a mistake in the math in the last part.. it is corrected momentum of the truck changes same as the momentum of the volkswagen because momentum is conserved that means what one gains one must loose..

do to newtons law equal but opposite forces they both experience the same FORCE

JUST different direction

say the mack truck is M = 10*m

where m = mass of the volkswagen

F = m*a

if both have the same force the acceleration on the volkswagen will be

a = F/m

=========

b = F/M let b = acceleration on the mac truck

b = F/(10*m) = (1/10)F/m = (1/10)* a

so we see the mack truck experiences LESS acceleration

==============

this im not sure of I am a bit tired

if both are travelling at the same speed when they collide

momentum must be conserved

M*v + m*(-v) = (M + m)* w

10*m*v + m(-v) = ( 10m + m) * w

9 m*v = 11 m * w

(9/11)*v = w

there fore w will be lower then the initial velocity of the mack truck

but since the mack truck has more mass it will keep travelling in the same direction as the mack truck just crushed together..

the mack trucks momentum changes from M*v to M * w

M*w - M*v = M*(9/11) v - M*v
= -(2/11)M*v
from our assumption M = 10 * m
= -(2/11)*10*m*v
= -20/11)*m*v
=============

the volkswagen

starts out with a momentum of - mv and ends with a momentum of m*w
remember the first velocity was going in the opposite direction to the final so we have the - inside the bracket
this is where i made the mistake... this is wrong
m*w - ( -m*v) = m* (9/11) v - (-m* v) = m (10/11)v

CORRECTION MADE HERE
correct way is

m*w -(m*v) = 9mv/11 + mv

we need a common denominator
9mv/11 + 11mv/11 = 20 mv

this means the volkswagen gains the amount of momentum the Mack truck had lost..
