Question

Travels at

a speed of 80 m/s. It has an estimated mass of 480,000.0 kg. What is the maximum
KE of this train ?

Answer 1

KE= 1,536,000,000 Joules

Step-by-step explanation:

The equation to find Kinetic Energy (KE) is

`KE=(1)/(2)mv^(2) \\`

You are given

m=480,000.0 kg

v= 80 m/s

Substitute the values into the equation and solve for KE

`KE= (1)/(2)* 480000*80^(2)`

KE= 1,536,000,000 Joules
