Asmall 16 kilogram canoe is floating downriver at a speed of 3 m/s. what is the canoe's kinetic energy?

72 Joules.

Step-by-step explanation:

kinetic energy(K.E) is the energy possessed by a body in motion.

K.E = 1/2×mv²

where m is the mass and v is the velocity/speed of the body in motion.

K.E = 1/2×mv²

      = 1/2 × 16 × 3²

      = 1/2 × 16 × 9

       = 72 Joules.

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
