A hawk is chasing a sparrow. At the beginning of the chase, the hawk’s kinetic energy is 5.1 Joules. At the end of the chase, the hawk doubles its speed. What is the best prediction for its kinetic energy at the end of the chase?(1 point)
The best prediction for the hawk's kinetic energy at the end of the chase is 20.4 J because the kinetic energy is directly proportional to the square of the velocity. Since the hawk doubles its speed, the kinetic energy will increase by a factor of 2^2 = 4. Multiplying the initial kinetic energy of 5.1 J by 4 gives us 20.4 J.
