A space shuttle is in a circular orbit at an altitude of 103 mi. Calculate the absolute value of g at this altitude and determine the corresponding weight of a shuttle passenger who weighs 165 lb when standing on the surface of the earth at a latitude of 45°. Are the terms "zero-g" and "weightless," which are sometimes used to describe conditions aboard orbiting spacecraft, correct in the absolute sense? Answers: ft/sec² gh = Wh lb = i i

The 18 000-kg F-35B uses thrust vectoring to allow it to take off vertically. In one maneuver, the pilot reaches the top of her static hover at 200 m. The combined thrust and lift force on the airplane applied at the end of the static hover can be expressed as F = (44t + 2500t2)i + (250t2 + t + 176 580)j, where F and t are expressed in newtons and seconds, respectively. Determine how long it will take the airplane to reach a cruising speed of 1000 km/hr (cruising speed is defined to be in the x-direction only).
Person A lifts a 10 kg box vertically upward to a height of 2 meters. Person B pushes 10 kg box up an inclined ramp with friction to a height of 2 meters.
