Final answer:

The kinetic energy of the sheep is 291.6 Joules and the kinetic energy of the lamb is 91.125 Joules.

Step-by-step explanation:

The question is asking to calculate the kinetic energy of a sheep and lamb running towards a kraal. Kinetic energy can be calculated using the formula:

Kinetic Energy = 1/2 * mass * velocity^2

For the sheep with a mass of 80 kg and a velocity of 2.7 m/s:

Kinetic Energy = 1/2 * 80 kg * (2.7 m/s)^2 = 291.6 Joules

For the lamb with a mass of 25 kg and a velocity of 2.7 m/s:

Kinetic Energy = 1/2 * 25 kg * (2.7 m/s)^2 = 91.125 Joules
