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. Calculate for the: (a) initial position of the lander; (b) initial velocity of the lander; and (c) initial acceleration of the lander.

In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition. More precisely, show that (a) 1.0m/s=3.6km/h and 1.0m/s=2.2mi/h .
