Answer:
15,569,653.3 Joules(J)
Explanation:
The equation used to find Kinetic Energy (KE) is
KE = [tex]\frac{1}{2}[/tex] m [tex]v^{2}[/tex]
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 = [tex]\frac{1}{2}[/tex] m [tex]v^{2}[/tex]
KE = [tex]\frac{1}{2}[/tex] * 450 * [tex]263.056^{2}[/tex]
KE = 15,569,653.3 Joules(J)
Round your answer as appropriate
