Homework Statement
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.
Homework Equations
w = -3.6736e11 J (I figured this out from a question before it that I didn't post)
F = W/(s(cos(theta)))
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.
