Asmall 20-kilogram canoe is floating downriver at a speed of 2 m/s. what is the canoe's kinetic energy?

40 Joules

Explanation: Kinetic energy is the energy possessed by a body by virtue of its motion.

Kinetic energy depends on the mass and speed of the object.

m= mass of canoe = 20 kg

v= speed of canoe = 2 m/s

i think it's 35 meters

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
