The millersburg ferry (m = 13000.0 kg loaded) is travelling at 11 m/s when the engines are put in reverse. the engineproduces a force of 1.0 x 106n for a period of 20.0 seconds. a)what is the magnitude of the impulse from the engine? b)what is the new momentum of the ferry? c)what is the new velocity of the ferry?

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

that would be because of both gravity and friction. so     c
