A rock is thrown upward from the top of a 25 foot tower with an initial upward velocity of 100 ft/sec. Write an equation that models the height of a rock above the ground as a function of time. (Vertical Motion Equation: h(t)=-16t^{2}+vt+sh(t)=−16t 2 +vt+s) What is the maximum height the rock reaches? How long does it take the rock to reach the maximum height?

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
