11. A ball is shot from a cannon into the air with an upward velocity of 40 ft/sec. The quadratic function that gives the height h of the ball at any time t is: h = -16t² + 40t + 1.5. a) How high did the cannon ball go? b) How much time passed before the cannon ball hit the ground (height of 0)? c) When did the cannon ball reach a height of 20 feet? d) What is a reasonable domain and range for this situation?

b(I-n) +0= ,t The water depth in a harbor is 6 m at low tide and 14 m at high tide. One cycle is completed in 12 hours. a) Find the equation for the water depth, d(t) meters, as a function of the time, h hours, after high tide, which occurred at midnight. 240 A miz b) Algebraically find the times when the level of water is 11 meters during the first 12 hours

A potato is launched vertically upward with an initial velocity of 170 feet per second from a potato gun at the top of an 66-foot-tall building. The distance in feet that the potato travels from the ground after t seconds is given by s(t) 16+2 + 170t + 66. a) Find the velocity of the potato after 2.2 seconds and 7 seconds. At t = 2.2 seconds, v = At t = 7 seconds, v = feet per second. feet per second. b) Find the speed of the potato at 2.2 second and 7 seconds. At t = 2.2 seconds, the speed of the potato is At t = 7 seconds, the speed of the potato is c) Determine when the potato reaches its maximum height. t seconds Determine how long the potato is in the air. seconds. d) Find the acceleration of the potato at 2.2 seconds and 7 seconds. At t = 2.2 seconds, a = At t = 7 seconds, a = feet per second. Determine the velocity of the potato upon hitting the ground. feet per second. feet per second. feet per second per second. feet per second per second.
