Chapter 2, Problem 2.56P
CALC A lunar lander is descending toward the moon’s surface. Until the lander reaches the surface, its height above the surface of the moon is given by y(t) = b − ct + dt2, where b = 800 m is the initial height of the lander above the surface, c = 60.0 m/s, and d = 1.05 m/s2. (a) What is the initial velocity of the lander, at t = 0? (b) What is the velocity of the lander just before it reaches the lunar surface?
