A projectile is launched from ground level with an initial velocity of v 0 feet per second. Neglecting air resistance, its height in feet t seconds after launch is given by s= -16t^2 + v 0 t. Find the time(s) that the projectile will (a) reach a height of 80 ft and (b) return to the ground when v0 = 112 feet per second. (a) Find the time(s) that the projectile will reach a height of 86 ft when v 0= 112 feet per second. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632
