An assistant for a football team carries a 32.0 kg cooler of water from the top row of the stadium, which is a distance h = 22.5 m above the field level, down to the bench area on the field. The speed of the cooler is constant throughout the trip. Calculate the work WA done by the assistant on the cooler of water. WA = Calculate the work Wgrav done by the force of gravity on the cooler of water. Wgrav =
