Asmall 23 kilogram canoe is floating downriver at a speed of 3 m/s. what is the canoe's kinetic energy?

Kinetic energy is defined as the energy the object possess due to its motion. It is the work that accelerates a given body from rest to motion.

Given:

The mass of the canoe is 23 kilogram

The velocity of the canoe is 3 m/s

The kinetic energy can be given by the formula:

KE =

Substituting the given values in the kinetic energy equation

KE =

KE= 11.5 * 9 kg.m^2/s^2

k = 103.5 J

Therefore the kinetic energy of the canoe is 103.5 Joules.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
