A small 17 kilogram canoe is floating downriver at a speed of 4 m/s. What is the canoe's kinetic energy

Answer is: canoe's kinetic energy is 136 J.

m (canoe) = 17 kg.

v (speedcanoe) = 4 m/s.

E (canoe's kinetic energy) = ?

E = 1/2 · m (canoe) · v² (canoe).

E = 0,5 · 17 kg · 16 m²/s².

E = 136 J.

The kinetic energy of a non rotating object of mass m traveling at a speed v. The standard unit of kinetic energy is the joule.
