A ball is thrown straight upward from 18 ooblongs above the surface of Mars, with an initial velocity of 16 ooblongs per second. (An ooblong is a unit of distance). The gravitational pull of Mars is equal to 4 ooblongs per second per second. Answer the following questions about this Martian ball. (4 points each) a. Express the velocity of the ball as a function of time. b. Express the height of the ball as a function of time. 2'3: Ie—LH: a = W— 2+‘+ C 4% Jm=meeaw c. How lon will it b unil th bll hits teoun‘?

You have estimated the area under the increasing function f(x) between x=2 and x=7, and above the x—axis, by using ten inscribed rectangles of uniform width, as shown below. Your estimate is 35. Now you would like to estimate the same area, but this time using ten circumscribed rectangles of uniform width. Given that f(2)=3 and f(7)=10, what is your new estimate? Show your work.
