Amotorboat accelerates uniformly from a velocity of 6.5 m/s to the west to a velocity of 1.5 m/s to the west. if its acceleration was 2.7 m/s2 to the east, how far did it travel during the acceleration?

7.407 m

Explanation:

Let the west direction is positive so the east direction is taken as negative.

initial velocity, u = 6.5 m/s

Final velocity, v = 1.5 m/s

acceleration, a = - 2.7 m/s^2

Let it travels a distance s during this acceleration.

Use third equation of motion, we get

s = 7.407 m

Thus, the distance traveled is 7.407 m.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
