Kinetic energy is expressed through the formula Ke=1/2mv^2, where Ke is measured in Joules (kg•m^2/s^2). For this problem, just plug in the given values:
Ke=1/2mv^2
Ke=1/2(22kg)(1m/s)^2
Ke=1/2(22)(1)
Ke=11
This canoe, with a weight of 22 kg and a speed of 1 m/s, has a kinetic energy equal to 11 Joules.
