1. Calculate the length of time it would take an object to fall 10.0 m if g were one-sixth the value of Earth's g (the acceleration due to gravity on the Moon).

2. A ball is thrown straight down at 12 m/s toward the ground from a height of 45 m. T/I (a) How long does it take to land? (b) How fast is the ball moving when it lands? (c) How does your answer to (b) change if the ball is initially thrown at 12 m/s [upward]?
