A farmer is walking through a field at a velocity of +0.5 meters per second (m/s) relative to the ground. At the same time, he is throwing seeds in front of him at a velocity of +2.1 m/s relative to himself. What is the velocity of the seeds relative to the ground as they travel through the air?

The velocity of the seeds relative to the ground as they travel through the air is 2.6 meters per second.

Explanation:

From Physics, we know that the absolute velocity of the seeds () is the sum of the absolute velocity of the farmer () and the velocity of the seeds relative to the farmer (), all measured in meters per second. That is:

(1)

If we know that and , then the velocity of the seeds relative to the ground is:

The velocity of the seeds relative to the ground as they travel through the air is 2.6 meters per second.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
