Question

A form of this quantity is given by the square root of mu over a, and its square is the characteristic energy; that is this quantity’s “hyperbolic excess.” Since the rate of specific energy change is this quantity dotted with acceleration, specific energy gains are highest when this quantity is highest by the Oberth effect. Space mission planning often computes the “budget” in this quantity’s delta, which (15[1])can be calculated using the (*) Tsiolkovsky (10[1])rocket equation. The square root of 2GM over r gives a threshold value for this quantity (10[1])in a gravitational field. (10[2])For a constant-mass object, (-5[1])the object’s mass times the change in this quantity gives the impulse on the object. For 10 points, (-5[1])to exit Earth’s gravity, an object must attain the “escape” (10[1])form of what quantity? ■END■ (10[2])

ANSWER: velocity [or speed; accept delta V or change in velocity or delta V budget; accept hyperbolic excess velocity or escape velocity]
