While attempting a landing on the moon, astronauts had to change their landing site and land at a spot that was 4 kilometers away from the original site. assuming that they were at a height of 137 meters, calculate the horizontal velocity of the spacecraft during touchdown if it lands in a free-fall mode without using retro engines. consider gravity = 1.63 meters/second^2.
a) 143.23 meters/second
b) 233.33 meters/second
c) 308.88 meters/second
