Question 1205987

given:

{{{m=52kg}}}
{{{K=1.6*10^4*J}}}
 


the kinetic energy is

{{{K=(1/2)mv^2}}}  where {{{m}}} is the mass and {{{v}}} is the velocity


{{{1.6*10^4*J=(1/2)*52*v^2}}}


since {{{1J=1km^2/s^2}}}


{{{(1.6*10^4*(km^2/s^2))/(52/2)=v^2}}}


{{{v^2=615.3846153846155(km^2/s^2)}}}


{{{v=sqrt(615.3846153846155(km^2/s^2))}}}


{{{v=24.81(km/s)}}}
