Respuesta :

KE = 1/2mv^2
m=10 v=3
KE=1/2*10*3^2
KE= 45 Joules

answer

45J

explanation

kinetic energy can be found through the equation [tex]K = \frac{mv^2}{2}[/tex]

plug in 10 for m (mass) and 3 for v (velocity)

[tex]K = \frac{mv^2}{2}\\K = \frac{10*3^2}{2}\\K = \frac{10*9}{2}\\K = \frac{90}{2}\\K = 45 J[/tex]
