Conservation of energy question?
Early test flights for the space shuttle used a glider "(mass of 950 kg with driver). After launched horizontally 138.9 m / s at a height of 3200 meters, the aircraft finally landed at a speed of 61.11m / s. What was the average force of air resistance exerted on him if he was at a constant slip angle of 12 degrees to Earth's surface? Thank you-nik
Well, it's not so difficult. Average force is energy divided by distance. You have a change of (Energy ½ mv ²) and the severity of the kinetic energy (mgΔh). The distance can be calculated by the change in altitude (Δh) and the angle of descent. Divide by the distance of energy, here: the average strength.
