Sagot :
It is calculated that each person required 656.91 J of metabolic energy to finish the course.
How is energy formed?
When electrons transfer by one atom to the next, energy is produced. Energy can also take the form of heat or light. It is also possible to convert one type of energy into another. Potential energy that has been stored converts to electric energy using a battery.
Briefing:
The following formula is used to determine Jessie and Jaime's kinetic energy:
K.E = ¹/₂mv²
where;
m is mass of Jaime
v is speed
15 km/h = 4.17 m/s
4 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, it is calculated that each person required 656.91 J of metabolic energy to finish the course.
