## Homework Statement

A 1015 kg automobile hits a tree at 32 m/s, coming to a complete stop in 0.03 s. What force was applied to the car by the tree? (Take the forward direction of the car as positive).

## Homework Equations

i dont know what would be relevant.

f=m/a

f (cos theta) d

## The Attempt at a Solution

the answer from the teacher is 1082667 J but i dont know how youre supposed to find that. i think im missing some equation. i looked through everything cant really find one that has to do with mass velocity and time for a force. and i have no idea how to make up equations. well i probably could but it wouldnt be right.

thank you!
