Question: Early test flights for the space shuttle used glider (mass of 980kg including pilot) that was launched horizontally at 500km/h from a height of 3500m.

Early test flights for the space shuttle used “glider” (mass of 980kg including pilot) that was launched horizontally at 500km/h from a height of 3500m. The glider eventually landed at a speed of 200km/h.
(a) What would its landing speed have been in the absence of air resistance?
(b) What was the average force of air resistance exerted on it if it came in at a constant glide of 10o to the Earth?
