Chapter 5, Problem 43RE

Motion on the moon The acceleration due to gravity on the moonis approximately g/6 (one-sixth its value on Earth). Compare thetime of flight, range, and maximum height of a projectile on themoon with the corresponding values on Earth.

complete) A rock thrown vertically upward from the surface of the moon at a velocity of 4 m/sec reaches a height of s= 4t-0.8t meters in t sec. a.
