Physics (10th Edition)

The boat is accelerating to the west at $0.31m/s^2$.
1. Draw the free body diagram: ** I'm going to consider east as the positive x direction. 2. Now, calculate the net force: F = $(-4100N) + (800N) + (1200N) = -2100N$ 3, Now, calculate the aceleration. $F = ma$ $-2100 = 6800a$ Divide both sides by 6800: $\frac{-2100}{6800} = a$ $a = -0.31m/s^2$ So, the boat is accelerating to the west at $0.31m/s^2$.
