An astronaut wearing a 20-kg spacesuit jumps on the Moon with an initial velocity of 16 m/s. On the Moon, the acceleration due to gravity is 1.62 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.
