A 0.40 kilogram bird is flying at a constant speed of 8.0 m/s. What is the bird's kinetic energy?

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

for this one it would be d bump/forearm pass
