Can you help me with this please, an aproach on how to proced would be great.

1. The problem statement, all variables and given/known data
From top of a tower two bodies are dropped with the same velocity Vo and same inclinations $$\alpha$$1 $$\alpha$$2. both bodies fall in the same point of the ground. Calculate the hight of the tower.

Thank you.

The question makes no sense.
Have you stated it correctly?

From top of a tower two bodies are thrown with the same velocity (Vo) and same inclinations LaTeX Code: \\alpha 1 LaTeX Code: \\alpha 2. both bodies fall in the same point of the ground. Calculate the hight of the tower.

Hi,
yes that is the question, I am also confused..

Is there a diagram shown in the book? If not, can you draw a diagram of what you think is happening?

No there is not a diagram,

the answer is: H = (2v^2/g). (cos$$\alpha$$1 cos$$\alpha$$2 . cos($$\alpha$$1+$$\alpha$$2))/sen^2($$\alpha$$1+$$\alpha$$2)

But I can get the relation of combinig the movement of both bodies, as is in the problem both have the same intial velocity and angle.
