A hardworking ant must supply 0.00805 N to pull a small piece of fruit at constant velocity over a distance of 8.20 cm up a small hill to the entrance of the colony. If the coefficient of kinetic friction between the piece of fruit and the 23.0° sloped hill is 0.500, calculate the work done by the ant by pulling the piece of fruit up the hill.
Use the work-energy theorem to calculate the mass of the piece of fruit in grams. (The acceleration due to gravity is 9.81 m/s2.)
What is vertical component of the acceleration
