An assistant for a football team carries a 26.0 kg cooler of water from the top row of the stadium, which is a distance h = 20.5 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 done by the assistant on the cooler of water Number Calculate the work done by the force of gravity on the cooler of water. Number

i. Workdone on cooler = 5223.4 J

ii. Workdone by gravity on cooler = 5223.4 J

Explanation: see attachment

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
