Answer:
Ari catches up to Amanda at 19.3 meters
Explanation:
We have given Ari is swimming a 25-meter race.
It is given that after swimming 6 meters she catches up to Amanda in a ratio of 7:3 from the 6-meter mark.
So ,The distance between 6 meters and 25 meters = 25-6 =19 meters
It is given that she catched Amanda in ratio 7:3
So, she catched her at of the distance
So, the distance at which she catched Amanda
Ari catches 13.3 metres from 6 m marks
So the total distance = 13.33+6 =19.33 meters
So Ari catches up to Amanda at a distance of 19.33 meters

<h3>What is Potential and Kinetic energy?</h3>
Potential energy is the energy that is stored in any item or system as a result of its location or component arrangement. The environment outside of the object or system, such as air or height, has no impact on it. In contrast, kinetic energy refers to the energy of moving particles inside a system or an item.
mass of rod, mab = 2.4kg
mass of rod, mbc = 4kg
conservation of energy
potential energy at position 1,
V1 = 2.5 * 9.81 * 0.18 + 4 * 9.81 * 0.18
V1 = 11.30112
kinetic energy T1 at position 1 is zero
potential energy at position 2 is zero
K.E at position 2,
= 1/3 *4 * (0.36)²
=0.10368kg m²
= 1/12 *4 * (0.6)²
=0.12kg m²
on putting the values in above equation we get,
T₂ = 1.0667vb²
0 + 11.30112 = 1.0667vb² + 0
vb = 3.2549 m/s

Let the Blaise runs for time "t" to complete the race
so the total distance he moved is given by
Now Issac runs for time t = "t - 2*60"
because it took rest for 2 minutes
now it is given that Blaise wins by 10 m distance
now the distance moved by Blaise is given by
