Question

Early test flights for the space shuttle used a "glider" (mass of 980 kg including pilot). After a horizontal launch at 470 km/h at a height of 3200 m , the glider eventually landed at a speed of 230 km/h . Part A What would its landing speed have been in the absence of air resistance? Express your answer using two significant figures. v v = nothing km/h Request Answer Part B What was the average force of air resistance exerted on it if it came in at a constant glide angle of 13 ∘ to the Earth's surface? Express your answer using two significant figures.
