The question is asking to calculate the object's speed v1, v2, v3 at the certain time is the given of the problem, in my calculation, I would say that the speed would be 2m/s, 1.5m/s, 0.22m/s. I hope you are satisfied with my answer and feel free to ask for more if you have question and further clarification

Answer:
24.5 N
Explanation:
The falling object experiences its weight acting downwards and the air resistance in the opposite direction.
The air resistance increases with velocity so there may come a point, depending on the shape of the object and if there is sufficient height, where these 2 forces are equal.
Since the object has no net forces acting on it it will, according to Newton, no longer accelerate but continue with a constant velocity.
This is called Terminal Velocity.
So:
Air resistance = weight
R

R

2.5

9.8 = 24.5N
It would still be eastward because The direction of the velocity vector is always in the same direction as the direction which the object moves.
If a = 23 and b = 45
a + b = ?
23 + 45 = 68
