During the first and third quarter moon phases, there isn’t much difference between the ocean level during high tide and low tide. What is the name of the tide that occurs during these moon phases? Why is it smaller than tides at other times in the lunar cycle? Your

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
