What was the launch speed of the rocket? Assume the propellant is burned very quickly at blastoff.

How high will the rocket go?

You need to use the relationship that Vf

You are given 2 distances here. Choose one formula from launch.

Vo

You also know that since gravity is slowing things down that

Vb = Vt + .14 (9.8) where Vt is velocity at the top of the window.

Then you can make use of the other equation to the top of the window:

Vo

3 equations. 3 unknowns. Solve.

What have you tried? You have some of the values. And you have 3 equations that relate the variables you don't have to each other.

You need to use algebra to solve the equations and eliminate your unknowns.
