Question

A small 21 kilogram canoe is floating downriver at a speed of 1 m/s. What is the canoe's kinetic energy?

Answer 1

Kinetic energy is the energy of a moving object.
Kinetic energy can be calculated using the following equation;
K.E =
`(1)/(2) m v^(2)`
where - m - mass of object
v - speed of object
substituting the values in the equation
K.E = 1/2 x 21 kg x (1 m/s)²
K.E = 10.5 J
