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 = 710m is the initial height of the lander above the surface, c = 64.0m/s, and d = 1.03 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?
