Solve the problem.The height of a projectile launched at an angle of ? degrees from the ground with an initial velocity v0 from a starting height of s can be found using the formula y = -16t2 + v0 ? sin(?)t + s. A projectile is launched from a height of 25 feet at an angle of 30° from the ground with an initial velocity of 140 ft/s. Find the maximum height that the projectile reaches, using the fact that sin(30°) = 0.5. When computing maximum height in the following problem, round both the time and the computed height to the nearest tenth.
