Answer:
12.8 J
Explanation:
Kinetic Energy: This can be defined as the energy posses by a body due to its motion. The S.I unit of kinetic energy is Joules(J)
From the question,
Ek = (1/2)mv²........................... Equation 1
Where m = mass of the bird, v = speed of the bird.
Given: m = 0.40 kg, v = 8.0 m/s.
substitute these values into equation 1 above,
Ek = 1/2(0.4)(8²)
Ek = 0.2(64)
Ek = 12.8 J
