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

Answers

Answer 1
Answer:

Answer: 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.

K.E=(1)/(2)* mv^2

m= mass of canoe = 20 kg

v= speed of canoe = 2 m/s

K.E=(1)/(2)* 20kg* (2m/s)^2

K.E=40kgm^2s^-{2}=40Joules

(1kgm^2s^(-2)= 1Joule)
Answer 2
Answer: Ek=1/2mv^2 = (20)(1/2)(2x2) =40
