Early test flights for the space shuttle used a "glider" (mass of 960 kg including pilot). After a horizontal launch at 480 km/h at a height of 3200 m , the glider eventually landed at a speed of 230 km/h .

What would its landing speed have been in the absence of air resistance?

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?

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
