Answer:
a) in uniform motion
Explanation:
When velocity-time graph is parallel to x-axis, it shows that the object is moving with constant velocity. or we can say that that the object is moving with uniform motion. There is no change in velocity. It covere equal distance in equal intervals of time.
Hence, the correct option is (a) "in uniform motion".
The ball needs to accelerate with a magnitude <em>a</em> (pointed towards the center of the circle) of
<em>a</em> = (5.0 m/s)² / (2.0 m) = 12.5 m/s²
Then the required tension <em>F</em> in the string would need to be
<em>F</em> = (2 kg) (12.5 m/s²) = 25 N
