Explanation:
Given parameters:
Mass of fish = 1kg
Velocity = 12m/s
Unknown:
Change in kinetic energy = ?
Solution:
Kinetic energy is the energy due to the motion of a body. It is mathematically given as:
K.E =
m v²
Now, insert the parameters and solve;
K.E =
x 1 x 12 = 6J
The change in kinetic energy is 6J
