Respuesta:
H = 14.08 m
Explicación:
vo = 0m/s
Tramo AB
H - 2 = vot + 1/2gt²
H - 2 = 4.9t²
Tramo AC
H = vot + 4.9 ( t + 0.125)²
H = 4.9 ( t + 0.125)²
Remplazamos:
4.9 ( t + 0.125)² - 2 = 4.9t²
4.9 (t² + 0.25t + 0.015625) - 2 = 4.9t²
1.225t + 0.0765625 = 2
t = 1.57s
H = 4.9 ( t + 0.125)²
H = 4.9 (1.695)²
H = 4.9 * 2.873
H = 14.08 m
