Question

If an airplane has a rest mass of 20,000 kg , what is its relativistic mass in the alternate universe when it is moving at 180 m/s

Answer 1

If an airplane has a rest mass of 20,000 kg, Relativistic mass in the alternate universe when it is moving at 180 m/s will be 25,000 Kg.

Relativistic mass = rest mass / $\sqrt{1-(\frac{v}{c} )^{2}$

where.

V = Speed

C = Speed of light

m = 20,000 / $\sqrt{1- (\frac{180}{3 * 10^{8} })^{2} }$

Relativistic mass = 25,000 Kg

What is rest mass and relativistic mass?

Two types of mass are recognized in the theory of special relativity: relativistic mass, which is dependent on the observer's velocity, and invariant mass, sometimes known as rest mass since it has a constant value that is the same for all observers across reference frames.

Why is relativistic mass important?

Relativistic mass is used to characterize the mass changes that take place when light interacts with matter since, for instance, the photon has a relativistic mass while not having a rest mass.
