i dont know what would be relevant.
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.
