- For exercise, an athlete lifts a barbell that weighs 400 N from the ground to a height of 2.20 m at a constant speed in a time of 1.60 s. What is the metabolic power, in kW (kiloWatts)? Your answer needs to have 2 significant figure, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.A bucket of water of mass 20 kg is pulled at constant velocity up to a platform 45 meters above the ground. This takes 18 minutes, during which time 8 kg of water drips out at a steady rate through a hole in the bottom. Find the work needed to raise the bucket to the platform.
