The answer is 6624000J.
Given mass = 0.046 kg
speed= 0.75 c=2.099[tex]\times[/tex][tex]10^8[/tex]m/s
we know that K.E=[tex]\frac{1}{2} \times m\times v^2[/tex]
KE=[tex]\frac{1}{2} \times0.046\times2.88\times10^8[/tex]
KE=6624000J
What is kinetic energy?
- The energy an item has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.
- The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.
- The energy that an item has as a result of motion is known as kinetic energy. Essentially, it is the energy of a moving mass. Kinetic energy is a scalar quantity, meaning that it only supplies the magnitude and not the direction of an event. It can never be negative.
