**Exercise 8: Calculating Power Exerted by a Tractor**

A tractor is pulling a 4-ton wagon uphill on a slope with a 15° angle of inclination at a speed of 7.2 km/hr. Calculate the power exerted by the tractor under the following conditions:

a) If the wheels have no resistance to rolling.

b) If the wheels have resistance to rolling and the Coefficient of Rolling Resistance (CRR) is 0.08.

(Note: The exercise refers to a physics calculation involving force, energy, and power concepts related to mechanics.)
