The most massive Shinkansen bullet trains are the series-200 trains. This type of train also has one of the highest operating speeds: 76.4 m/s. If a series-200 train has a maximum kinetic energy of 2.78 x 10° J, what is its mass?​

From the calculations that we carried out, the mass of the body is 9.5 x 10^6 Kg.

What is kinetic energy?

Kinetic energy is the product of mass and velocity. The kinetic energy of a body is the energy possessed owing to the motion of the body.

Given that;

KE = 1/2 mv^2

KE = kinetic energy

m = mass

v = velocity

m = 2KE/v^2

m = 2 * 2.78 x 10^10 J/( 76.4 m/s)^2

m = 9.5 x 10^6 Kg
