Question

How high would a projectile go if it was launched from ground level with an initial speed of 26 m/s at an angle of 30 degrees above the horizontal?

Answer 1

Vy = 26 m/s sin 30 = 13 m/s vertical speed

t = Vy / a = 13 m/s / 9.80 m/s^2 = 1.33 sec time to reach Vy = 0

H = Vy t + 1/2 g t^2

H = 13 m/s * 1.33 sec - 1.33^2 * 9.8 / 2 m = 8.62 m
