Angular velocity with aircraft (equation help?)

[littlejim]

Homework Statement

A 2100lb airplane requires a power of 100 HP at the propeller to climb at an angle of 20 degrees to the horizontal at a constant speed. how much altitude could it gain in 10 minutes?

Homework Equations

that's actually what I need help on...i left my book at school and I don't have the equations on hand. Can someone point me in the right direction here firstly please? This doesn't seem that hard but I haven't a clue what equations i should be using.

The Attempt at a Solution

N/A (for now, sorry)

Try these equations:

P=Fv
Ep=mgh
Fg=mg

I would recommend starting by identifying the relevant equations for this problem. In this case, we can use the equations for power, work, and torque to calculate the angular velocity of the propeller. From there, we can use the equation for rotational motion to determine the change in altitude over time. It is also important to consider the forces acting on the airplane, such as gravity and lift, to accurately calculate the altitude gained. It may be helpful to refer to your textbook or lecture notes, or do some research online to find the specific equations needed for this problem.
