A boat, with a mass of 150kg, stars at rest with an acceleration of +1.5 m/s2 when going in the same direction of the current and engine at its fullest. In a second experiment, the boat, with the same mass, departs from rest in the direction opposite to the current, also at full engine performance. In this second case the acceleration of -1.0m/s2. A Diagram follows.
Ignoring Friction
a) Draw the appropriate Free Body Diagrams
b) FindThe Force applied by the engine.
b) The Force of the current

II) When Friction is 20N, and Fboat and FCurrent are the same as in I.
