You can describe the motion of an object by its position, speed, direction, and acceleration
The constant force required is 17.6 N
<u>Explanation:</u>
Given-
Mass, m = 0.55 kg
Initial speed, u = 0
Final speed, v = 8 m/s
Time, t = 0.25 s
Force, F = ?
We know,
Force = mass X acceleration
F = 0.55 X
F = 0.55 X
F = 17.6 N
Therefore, the constant force required is 17.6 N

The velocity of the earth in its orbit around the sun is
Explanation
Given that the distance between sun and earth is 149500,000,000m
.
This is the radius of the nearly circular orbit of the earth around the sun.
r=149,500,000,000m=
