1) A ball is thrown vertically upward from a height of 6 ft with an initial velocity of 60 feet per second. How high will the ball go?
2) A farmer plans to fence a rectangular pasture adjacent to a river. The pasture must contain 180,000 square meters in order to provide enough grass for his herd. What dimensions would require the least amoung of fencing if no fencing is needed along the river?
3) A ladder that's 25 feet long is leaning aginst the wall of a house. The base of the ladder is pulled away from the wall at a rate of 2 feet per second. How fast is the top moving down the wall when the base of the ladder is 7 feet away from the wall? 15 feet? 24 feet? If the ladder is being pulled from the wall at a constant speed, why is the top of ladder not moving at a constant speed?
FYI, I did these already so thpthpthptph.
