Newton's third law is action is equal and opposite to reaction. Therefore 10 N
(That is way too little to pull a cart though.)
The two cars see the same force (Third law again
the lighter car will accelerate more
Mbig A big = m small a small
some of the possible answers to question # 1 is
4000n,10n,40n, not enough info or none of the above, would you recommend none of the above ?
for question # 2 you woud say the only answer would be that the lighter car has a greater acceertion due to the collison?
No, c alone. Both have the same force
the light one has greater acceleration. That is not one of your choices.
10 N is correct for the first one. Of course there is no way 10N will pull the cart. You probably weigh about m g = 60*9.8 = 588 N
okay . and for question # 1 you woud recommonded choosing none of the above correct ?
for question 1, 10 N is correct.
Unlikely but correct.
damon, does the car that weighs 500kg have more acceleration? if so, would e be correct then?
here's the bottom three choices again:
c. The two cars have the same acceleration due to the collision.
d. car at rest has the greater acceleration due to the collision.
e. The car that is moving has the greater acceleration due to the collision.
what you wrote was:
" e)The car at rest has the greater acceleration due to the collision. "
That is wrong.
Now you have changed the wording of e so it is right.
