Question

How much energy is required to accelerate a golf ball of mass 0.046 kg initially at rest to a speed of 0.75c?

Answer 1

The required energy to accelerate the golf ball is  $0.232875X10^{16} kg-m/sec^2$.

What is Energy?

• Energy, which is observable in the execution of labor as well as in the form of light and heat, is the quantitative quality that is transmitted to an object or to a physical phenomenon in physics.
• Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed.
• The joule, which is defined as "the energy transmitted to an object by the effort of moving it a length of one metre against a force of one newton," is the standard measure for power in the International System of Units (SI).

Given that,

E=$mc^2$

=$0.046X0.75^2Xc^2$

=$0.232875X10^{16} kg-m/sec^2$ .
