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.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
