(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The asteroid has a mass of 4.10 x 10^4 kg, and the force causes its speed to change from 7100 m/s to 5700 m/s.

If the asteroid slows down over a distance of 1.50 x 10^6 m, determine the magnitude F of the force.

2. Relevant equations

w = -3.6736e11 J (I figured this out from a question before it that I didn't post)

F = W/(s(cos(theta)))

3. The attempt at a solution

F = (-3.6736e11) / ((1.50 x 10^6)(cos(theta)))

I was just wondering how you would find theta for this problem.
