Compute the impact speed of a body released from rest at an altitude h = 426 mi. (a) assume a constant gravitational acceleration g0 = 32.2 ft/sec2 and (b) account for the variation of g with altitude. neglect the effects of atmospheric drag.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

Answer(b) both involve the use of levers;
