D. Mechanical energy remains unchanged.
Mechanical energy = Potential energy + Kinetic energy
So if potential energy decreases, then kinetic energy must increase so that the system is balanced.
The acceleration of the race car is 6 m/s²
The given parameters;
initial velocity of the race car, u = 6 m/s
final velocity of the race car, v = 36 m/s
time of motion, t = 5 s
Acceleration is defined as the change in velocity per change in time of motion.
The acceleration of the race car is calculated as follows;

Thus, the acceleration of the race car is 6 m/s²

Yes it is it is btw there is no picture if you were meaning to put one
Well the most obvious to me is “The cell can no longer maintain life.
Answer:
energy : the ability to cause change
work : is force x distance or when an object moves a distance due to a specific force (measured in units of newtons-meters)
potential energy : is stored energy
kinetic energy : is energy in motion
mechanicle energy : the energy of motion such as a moving vechile
thermal energy : total kinetic energy in moving partsticles, like in boiling water (energy of heat)
chemical : energy stored in chemical bonds, like in plants
electromagnetic : waves with electric and magnetic properties , such as light
nuclear energy : energy stored in the nuclear atoms
