Asmall 21 kilogram canoe is floating downriver at a speed of 4 m/s. what is the canoe's kinetic energy? answer = units =

As per this question the mass of canoe is given as 21 kg.

The canoe is floating downriver with a speed of 4 m/s.

We are asked to  calculate the kinetic energy of the canoe.

The kinetic energy is the energy due to the motion of the body.

If a body has mass m and it moves with a velocity v ,then its kinetic energy is defined as

we are given v= 4 m/s and m= 21 kg

Hence kinetic energy of canoe

                                                                 =168 Joule.

Hence the kinetic energy of the  particle is 168 Joule.

Here Joule is the unit of energy

divide the right side by the left side

0.024÷1.2=0.02 for example

what is the actual question though?
