Chapter 2: Problem 56
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 \(y(t) = b - ct + dt^2\) , where \(b =\) 800 m is the initial height of the lander above the surface, \(c =\) 60.0 m/s, and \(d =\) 1.05 m/s\(^2\). (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?
