An object is launched directly in the air at a speed of 144 feet per second from a platform located 12 feet in the air. the motion of the object can be modeled using the function f(t)=−16t2+144t+12, where t is the time in seconds and f(t) is the height of the object. when, in seconds, will the object reach its maximum height? do not include units in your answer.

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
