Leilani dropped an acorn from her tree house. It took 1.1 seconds to hit the ground below.
a) Find height in feet from which she dropped the acorn.
b) Leilani throws an acorn up. This takes 1.4 seconds to hit the ground. What was the initial upward velocity to the nearest tenth of a second?

| Formula: h = -1/2 gt^2 + VoT + Ho for height of an object under the force of gravity, with g = 32 ft/sec^2 or 9.8 m/sec^2
