Chapter 14, Problem 21P

Water falls over a dam of height h with a mass flow rate of Iv, in units of kilograms per second. (a) Show that the power available from the water is

P = Ivgh

where g is the free-fall acceleration. (b) Each hydroelectric unit at the Grand Coulee Dam takes in water at a rate of 8.50 × 105 kg/s from a height of 87.0 m. The power developed by the falling water is converted to electric power with an efficiency of 85.0%. How much electric power does each hydroelectric unit produce?

In a scene from The Avengers (the first one) Black Widow is boosted directly upwards by Captain America, where she then grabs on to a Chitauri speeder that is 15.0 feet above her and hangs on. She is in the air for 1.04 s. A) With what initial velocity was Black Widow launched?  1 m = 3.28 ft B) What was Black Widow’s velocity just before she grabbed the speeder?  Assume upwards is the positive direction.
In Dark Souls 3 you can kill the Ancient Wyvern by dropping on its head from above it.  Let’s say you jump off the ledge with an initial velocity of 3.86 mph and spend 1.72 s in the air before hitting the wyvern’s head.   Assume the gravity is the same as that of Earth and upwards is the positive direction.  Also, 1 mile = 1609 m.  A) How high up is the the ledge you jumped from as measured from the wyvern’s head?  B) What is your velocity when you hit the wyvern?
A) If Yoshi flings himself downwards at 9.76 miles per hour to hit an enemy 10.5 m below him, how fast is Yoshi traveling when he hits the enemy? 1 mile = 1609 m
