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 don't 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 don't know how youre supposed to find that. i think I am missing some equation. i looked through everything can't 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 wouldn't be right.
thank you!
