A small 17 kilogram canoe is floating downriver at a speed of 2 m/s. What is the
RideAnS [48]
<h2>Hello!</h2>

The answer is:

Answer: 34

Units: Joules

KE=34J

<h2>Why?</h2>

The kinetic energy is the work needed to accelerate an object to a determined speed.

The kinetic energy can be calculated using the following equation:

KE=\frac{1}{2}mv^{2}

Where,

m, is the mass of the object.

v, is the speed of the object.

So, we are given the information:

mass=17kg\\\\v=\frac{2m}{s}

Then, substituting and calculating we have:

KE=\frac{1}{2}mv^{2}

KE=\frac{1}{2}*17kg*(\frac{2m}{s})^{2}

KE=8.5kg*(\frac{4m^{2}}{s^{2}})

KE=34\frac{kg.m^{2}}{s^{2}}=34J

Have a nice day!
