1. The problem statement, all variables and given/known data
Suppose that a person is pulling a car with an acceleration of 6 m/s^2. If the reindeer triples the net force, what is the new acceleration?

2. Relevant equations
F=ma
where, m= mass, a= acceleration, F=force

3. The attempt at a solution
I really do not know what my teacher means by this problem.
I think the answer is 18 m/s^2.
Thank You

a = F/m

All you're doing is tripling the Net Force. So, what would happen?

I do not get what you are asking!

### Kawaii Physics

I derived a = F/m from F = ma.

Just think about it. All we're doing is tripling the net force. You can put numbers in for examples and see what happens.

What do you mean by put numbers in for examples?

when we triple the net force, A = F / m there will be a value of 3 next to the F. it looks like this A = 3F / M (if F increased by 3x and m stayed the same A would increase by a factor of 3 also)
this relation proves that the acceleration does increase by 3x. so 18 seems like the answer
