Question

Anakin Skywalker's pod racer has a mass of 450 kg. If the top speed of this racer is 947

km/h, what is the maximum kinetic energy it can have​

Answer 1

15,569,653.3 Joules(J)

Step-by-step explanation:

The equation used to find Kinetic Energy (KE) is

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

You have been given

m = 450kg

v = 947km/h

KE = ???

Firstly, we need to convert the km/h into m/s as this is the unit used in the KE equation

This can be done by dividing by 3.6

947km/h = 263.056m/s

Substitute you values into the equation

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

KE =
`(1)/(2)` * 450 *
`263.056^(2)`

KE = 15,569,653.3 Joules(J)

Round your answer as appropriate
