a diver is standing on a platform 24 ft. Above the pool. He jumps form the platform with an initial upward velocity of 8 ft/s. use the formula h(t)= -16t2 +vt+s, where h is his height above the wáter, t is the trime, v is his starting upward velocity, and s is his starting height. How long will take for himto hit the wáter? Launched. Round to the nearest tenth of a second.

Solution:

h(t)=-16t^2+8t+24 = 0

t=1.5

So it takes 1.5 seconds for himto hit the wáter
