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.
A. 99.3 feet
B. 125.1 feet
C. 118.4 feet
D. 101.6 feet
