The diagram shows the apparent motion of the sun across the sky?

The earth rotates west to east

Explanation:

Considering that the sun doesn't really move and the earth is rotating around the sun, and it is moving from east to west with us (the earth) facing it in which means the earth rotates around the sun west to east!

2.28 m/s²

Explanation:

Draw a free body diagram of the box.  There are four forces on the box:

Weight force mg pulling down.

Normal force Fn pushing up.

Applied force F pushing right.

Friction force Fn μ pushing left.

Sum the forces in the y direction.

∑F = ma

Fn − mg = 0

Fn = mg

Sum the forces in the x direction.

∑F = ma

F − Fn μ = ma

F − mg μ = ma

a = (F − mg μ) / m

a = (650 N − 150 kg × 9.8 m/s² × 0.21) / 150 kg

a = 2.28 m/s²
