Question

A small 19 kilogram canoe is floating downriver at a speed of 2 m/s. What is the canoe's kinetic energy?

Answer 1

KE = 1/2mv^2 = 1/2*Mass*Velocity Squared

KE = 1/2*19*2^2 = 38

The only thing that could make this answer incorrect would be if your teacher wanted you to convert kilograms to grams.

Hope this helps!!!

Answer 2

Answer:

Kinetic energy of the canoe is 38 Joules.

Explanation:

Given that,

Mass of canoe, m = 19 kilogram

Speed of flowing, v = 2 m/s

The kinetic energy of canoe is given due to its motion. Mathematically, it is given by :

$k=\dfrac{1}{2}mv^2$

$k=\dfrac{1}{2}\times 19\ kg\times (2\ m/s) ^2$

k = 38 J

Hence, this is the required solution.
