Ke=34J. The canoe's kinetic energy floating downriver at a speed of 2m/s and 17kg mass is 34J.
This is a problem of kinetic energy, which is a form of energy, known as motion energy. The kinetic energy of an object is that which is produced because of its movements that depends on its mass and velocity.
The kinetic energy is represented by the following formula: Ke = ½ mv². The kinetic energy is measured in Joules (J), the mass in kilograms (kg) and the speed in meters over seconds (m/s).
A small 17kg canoe is floating downriver at a speed of 2m/s. Let's calculate canoe's kinetic energy.
Ke= (17kg)[(2m/s)²]/2= 68/2 kg m²/s²=34J
