The engine is switched off so the only force acting horizontally is the frictional force on the ship.
Weightand the up thrust are the two equal force acting against each other in vertical direction enabling the ship to float on water b) This can be found using Newton's second law of motion, F-ma. when the engine is switched OFF the onlyforce acting is the frictional force on the ship and it is equal to cv.So, F ma ma since, fr - av 2 From the above equation acceleration depends on the velocity and the velocity depends on the frictional force.This means more velocity more friction and less velocity less friction. So,the acceleration is not constant with time.
The velocity of the boat can be written from equation of motion. Substitute the values iia αν 2 Since the boat is deceleration, the acceleration should accompany a negative sign.
So, 7m
