Answer:

kinetic energy: #10J#

Explanation:

The kinetic energy of an object can be calculated with the formula:

#color(blue)(|bar(ul(color(white)(a/a)color(black)(E_k=1/2mv^2)color(white)(a/a)|)))#

#ul("where")#:
#E_k=#kinetic energy
#m=#mass
#v=#velocity

To find the kinetic energy, substitute your known values into the formula.

#E_k=1/2mv^2#

#E_k=1/2(8kg)(5/2m/s)#

#E_k=color(green)(|bar(ul(color(white)(a/a)10Jcolor(white)(a/a)|)))#
