After performing a long equation using the conservation of mechanical energy you get a final answer that is negative. What does this mean? A. Because energy is scalar it means that the energy is less than 0.

B. Because energy is scalar it means that the energy was transferred somewhere else.

C. Because energy is a vector it means that the energy was destroyed in the opposite direction.

D. Because energy is scalar it means that the energy was destroyed.

The correct option is D.

Explanation:

The energy is the capacity to do work.

There are several types of energies.

1. kinetic energy : it is due to the motion of the body.

2. Potential energy : It is due to the position or the configuration of the body.

3. Mechanical energy: The sum of the kinetic energy and the potential energy is called mechanical energy.

The energy is a scalar quantity.

According to the law of conservation of energy, the energy can not be created and cannot be destroyed, it can transformed from one form to another.

When we get the mechanical energy negative, it means the energy was destroyed in some other forms of energy.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
