Question

7. Japan's fasted high speed "bullet" train known as the Shinkansen travels at a speed of

88.9 m/s. It has an estimated mass of 480,000.0 kg. What is the KE of this train?​

Answer 1

1,896,770,400J

Step-by-step explanation:

The equation to find Kinetic Energy (KE) is

KE =
`(1)/(2)` m
`v^(2)`

You are given

m = 480000kg

v = 88.9m/s

Substitute the values into the equation and solve for KE

KE =
`(1)/(2)` m
`v^(2)`

KE =
`(1)/(2)` * 480000 *
`88.9^(2)`

KE = 1,896,770,400 Joules(J)
