College Physics - Acceleration
posted by Anonymous .
A 1470-kg submarine rises straight up towards the surface. Seawater exerts both an upward buoyant force of 16070 N on the sub, as well as a downward resistive force of 1050 N. What is the submarine's acceleration?
net force= mass*a solve for a.
This is what I tried but it didn't work. Am I doing something wrong?
(16070+1050) = 1470a
Why did you add the forces, they are in opposite direction!
Well I tired the other way and it didn't work either. The answer is 0.418 but I can't figure out how.
net force= bouyant force- weight-resistive force
