A 10 ft by 15 ft rectangular cistern (storage tank for rainwater) has its top 30 ft below ground level. The cistern, currently full, is to be emptied for inspection by pumping its contents to ground level. Assume that the water at the location weighs 62.26 a. How much work is done to pump all the water out of the cistern? b. How long will it take a - hp pump, rated at 367 ft-lb/sec, to do the work in part (a)? c. How much work is done to pump all the water out of a spout 2 ft above the top of the cistern d. How long will it take a hp pump, rated at 367 ft-lb/sec, to do the work in part (c)?

1. Round off to FOUR DECIMAL PLACES for all calculations made.
A ball with mass 0.65 kg is thrown upward with initial velocity 5 m/s from the roof of a building 100 m high. Assume there is a force due to |v| air resistance of magnitude directed opposite to the velocity, where the velocity v is measured in m/s. 30 NOTE: Use g=9.8 m/s² as the acceleration due to gravity. Round your answers to 2 decimal places. a) Find the maximum height above the ground that the ball reaches. Height: m b) Find the time that the ball hits the ground. Time: seconds c) Use a graphing utility to plot the graphs of velocity and position versus time.
