Ahorse whose mass is m gallops at constant speed v up a long hill whose vertical height is h, taking an amount of time t to reach the top. the horse's hooves do not slip on the rocky ground, so the work done by the force of the ground on the hooves is zero (no displacement of the force). when the horse started running, its temperature rose quickly to a point at which from then on, heat transferred from the horse to the air keeps the horse's temperature constant.(a) first consider the horse as the system of interest. in the initial state the horse is already moving at speed v. in the final state the horse is at the top of the hill, still moving at speed v. write out the energy principle? esys = w + qfor the system of the horse alone. the terms on the left hand side should include only energy changes for the system, while the terms on the right hand side should relate to the surroundings (everything else).which of the following terms are equal to 0? 1w? echemical, horse? (mhorsec2)? khorse? ethermal, horseq
