kinetic energy:
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)|)))#
