1. The problem statement, all variables and given/known data Early test flights for the space shuttle used as a glider (mass of 980kg). After a horizontal launch at 480 km/h at a height of 3500m, the glider eventually landed at a speed of 210 km/h. What would its landing speed have been in the absence of air resistance? also, what was the average force of air resistance exerted on it if it came in at a constant glide angle of 12degrees to the earth's surface? I attempted the first question by calculating the vertical component of the velocity and then using the Pythagorean theorem to calculate compound velocity. However, how I am completely at a loss of how to approach the second part. Please help.
