[Vertical] Earth Astronauts land on a strange planet with a breathable atmosphere very much like Earth's. In their exploration, they time how long it takes for a rock to fall 2.3 m. After several trials with fancy equipment, they found an average time for the rock to fall to be 0.88 seconds. Next the astronaut decided to see how high he could jump. He jumped up 1.9 meters. How high can he jump on Earth? (Assume that his initial velocity is the same on both planets.)

5) [Vertical] Earth Astronauts land on a strange planet with a breathable atmosphere very much like
Earth's. In their exploration, they time how long it takes for a rock to fall 2.3 m. After several trials
with fancy equipment, they found an average time for the rock to fall to be 0.88 seconds. Next the
astronaut decided to see how high he could jump. He jumped up 1.9 meters. How high can he jump on
Earth? (Assume that his initial velocity is the same on both planets.)
6) [Horizontal-ish] An object moves along a line in a way described by the Position vs. Time graph,
below. Mark on the Time axis the times the object is speeding up. (Marking can be done by shading in
the segments of time when object is speeding up.) Explain.
