The force involved in the orbiting of the earth is gravity!
Answer: The distance covered by a certain object which is travelling at a certain speed is calculated through the equation,
d = (V₀)t + 0.5at²
where d is the distance, V₀ is the initial speed, a is deceleration, and t is the time. Substituting the known values,
85 = (V₀)(t) + (0.5)(-0.43 m/s)(t²)
Because we are not given with the initial velocity, our answer would remain as the equation which is written above.
Explanation: Hope this helps
The list of statements you included has no good descriptions at all.
Acceleration is a Vector, so speed and direction. If you change your direction you are also changing your acceleration because it's a vector.
Answer:
In a collision, there is a collision force which endures for some amount of time to cause an impulse. This impulse acts upon the object to change its velocity and thus its momentum
