By definition, the kinetic energy is given by:
 [tex]k = ( \frac{1}{2} ) (m) (v ^ 2) [/tex]
 Where,
 m: mass of the object
 v: object speed
 Substituting values we have:
 [tex]k = \frac{1}{2} (15) (5 ^ 2) [/tex]
 Doing the calculations we have
 [tex]k = 187.5 J [/tex]
 The energy unit is joules
 Answer:
 
the canoe's kinetic energy is:
 
[tex]k = 187.5 J[/tex]
