A boat leaves the dock at t = 0.00 s and, starting from rest, maintains a constant acceleration of (0.461 m/s2) i relative to the water. Due to currents, however, the water itself is moving with a velocity of (0.485 m/s) i + (2.16 m/s) j.

Whenever the net force on a moving object is zero its acceleration is
