Answer:

G. 6125

Explanation:

Step one:

given data

mass m=  2.5x10-3 kg

velocity v= 7000 m/s

Required

The kinetic energy

Step two:

The expression for the kinetic energy is

KE= 1/2m v^2

KE= 1/2*2.5x10^-3*7000^2

KE= 0.5*2.5x10^-3*7000^2

KE= 0.5*2.5x10^-3*49000000

KE= 0.5*122500

KE=6125J
