Question

A small 15 kilogram canoe is floating downriver at a speed of 5 m/s. What is the canoe's kinetic energy?

Answer 1

By definition, the kinetic energy is given by:

`k = ( (1)/(2) ) (m) (v ^ 2)`
Where,
m: mass of the object
v: object speed
Substituting values we have:

`k = (1)/(2) (15) (5 ^ 2)`
Doing the calculations we have

`k = 187.5 J`
The energy unit is joules
Answer:
the canoe's kinetic energy is:

`k = 187.5 J`
