Because the centripetal force is provided by spring for this apparatus, the centripetal force at a given distance r is fixed by the spring constant of the spring. therefore, mv^2 should be constant for a given radius r. calculate the quantity mv^2 for the four data points taken at the same radius r. describe the agreement of those values.
there were only 3 data points: 0.43825, 0.48825, and 0.53825 and the mv^2 were calculated for each which i have written below the question in the picture for each of the three data points (1.30, 1.27, and 1.40). what is the agreement of these values?

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?
