The mass of an object traveling at speed is , where is the speed of light and is the initial mass of the object.

(a) Find . Explain the relationship between limit and .

.

.

As the velocity of object approaches , the mass of the object will approach initial mass.

(b) What happens to the mass of an object if its speed were able to a approach the speed of light.

.

The mass of the object would begin to increase without bound.
