FREE FALL ON THE MOON FREE FALL ON THE MOON 1. A boy on Earth jumps straight upward with an initial velocity of 4.9 m/s. a. How long does it take for him to reach maximum height? b. At maximum height, what is his velocity? c. At maximum height, what is his acceleration? Explain your answer.2. An astronaut jumps on the Moon with an initial velocity of 16 m/s upward. On the Moon, the free-fall acceleration is 1.6 m/s2. (Assume that downward is the positive direction.) a. How long does it take him to reach maximum height? b. What is the maximum height he reaches? c. If you drew a velocity-time graph for the motion of the astronaut, what would be the slope of the line? d. Are the vectors for acceleration and initial velocity pointed in the same or different directions? Explain your answer.
