Formula del desplazamiento máximo
Emax = [Vo² Sen 2α]/g
reemplaza
120 = Vo².[Sen 2(40°)]/10
Vo² = 1200/Sen 80° = 1200/0.9848
Vo = 37.6177 m/s
Emax = [Vo² Sen 2α]/g

120 = Vo².[Sen 2(40°)]/10
Vo² = 1200/Sen 80° = 1200/0.9848
Vo = 37.6177 m/s
DM=(Vo²*Sen2a)/9
120=Vo²(Sen2*40°)/9.8
Vo²=120/Sen 80°
Vo²=120/0.984
Vo²=121.9m/s
