The total metabolic energy used by each to complete the course is determined as 656.91 J.
<h3>
Kinetic energy of Jessie and Jaime</h3>
The kinetic energy of Jessie and Jaime is calculated as follows;
K.E = ¹/₂mv²
where;
- m is mass of Jaime
- v is speed
15 km/h = 4.17 m/s
5 km/h = 1.39 m/s
K.E = ¹/₂(68)(4.17)² + ¹/₂(68)(1.39)²
K.E = 656.91 J
Thus, the total metabolic energy used by each to complete the course is determined as 656.91 J.
