QUESTION -
A 30 kg canoe is floating downriver at 2 m/s. What is the KE?
ANSWER -
GIVEN: MASS= 30 Kg, VELOCITY =2m/s.
As we know that
Kinetic Energy =1/2 m v^2
Substituting the given values,
K.E = 1/2 × 30 kg × (2 m/s) ^2
= 15 kg × 4 m^2 / s^2.
= 60 kg m^2 / s^2.
Therefore the kinetic energy is 60 kg m^2 / s^2.
