It would be a question whether the Earth is even moving or not — not how fast. In the geocentric model of the solar system, Earth does not rotate. Sun, moons, starts and planets surrounds the Earth and they’re the ones considered moving on specific axis (not the Earth).
Answer:
The acceleration of the crate is
Explanation:
Recall the formula that relates force,mass and acceleration from newton's second law;
Then in our case, we know the force applied and we know the mass of the crate, so we can solve for the acceleration as shown below:
Answer:
B) 18.5 m/
s west
Explanation:
Scalar quantity has MAGNITUDE only
Vector quantity has MAGNITUDE and DIRECTION
