Answer: d
Explanation:
For an object to move in a uniform circular motion, only force that acts on it is the centripetal force which acts along the line joining the object and center of the circular path. The acceleration also acts in the direction of force. The centripetal acceleration acts along the radius of the circular motion path.
In the given horizontal circle, the direction of the acceleration of the object points towards d.
From the calculations, the final momentum of B is 8.16 m/s
<h3>What is conservation of linear momentum?</h3>
According to the principle of the conservation of linear momentum, the momentum before collision is equal to the total momentum after collision.
This implies that;
MaUa + MbUb = MaVa + MaVa
Substituting values;
(0.08 kg * 0.5 m/s) + (0.05 kg * 0 m/s) = (0.08 kg * −0.1 m/s) + (0.05 kg * v)
0.4 = -0.008 + 0.05v
v = 8.16 m/s

I think it would be TRUE but I’m not 100% sure.... please let me know if I’m right or wrong
Answer:
speed
Explanation:
Given: an incomplete sentence
To fill: the blank
Solution:
Speed is not a vector quantity but a scalar quantity as it has magnitude but no direction.
Speed = Distance ÷ Time
You can calculate an <u>average</u> speed if you know both the total distance and the total time of the trip.
Average speed = Total distance ÷ Total time
