(1 point) A bucket of water of mass 30 kg is pulled at constant velocity up to a platform 25 meters above the ground. This takes 20 minutes, during which time 2 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. (Use g = 9.8m/s².). Work = (include units)

Answer 9 Question 2 (1 point) Saved Calvin was sitting high up in a stadium watching a soccer match when he caught the soccer ball that went out. He threw the ball with a velocity of 0.0085 km/s from a height of 62 m above the ground at an angle of elevation of 37.5º. What was the magnitude of the vertical velocity of the soccer ball 4 s after it was thrown? Give your answer in metres/second. 2 a) 26.96...
