Given Problem
At the bow of a ship on a stormy sea, a crewman conducts an experiment by standing on a bathroom scale. In calm waters, the scale reads 180 lb. During the storm, the crewman finds a maximum reading of 234 lb and a...

Given Problem
A shopper pushes a 6.1 kg shopping cart up a 13° incline, as shown in the figure. Find the magnitude of the horizontal force, F, needed to give the cart an acceleration of 1.51 m/s2.

F = ma
Fy = F1cos13°...
Thank you =] Made the correction but apparently my answer has the wrong sign? Answer should be in x direction which I thought was what I was finding. Slightly confused =/
Thank you very much!
Made correction to Part B and treated m2 and m3 as a single block:
F = (m2 + m3) * (a)
F = (3.20kg + 4.30kg) * (.852273m/s2)
F = (7.5kg) * (.852273m/s2)
F = 6.39205 N
