The following text describes four different stars. Using the Hertzsprung-Russell diagram from earlier in the companion, determine whether each star is a giant, supergiant, white dwarf, or main sequence star:
Star 1:Color: Red-orange Surface temperature: 4000 K Luminosity: approximately 100 times dimmer than Earths Sun
Star 2:Color: Yellow Surface temperature: 5100 K Luminosity: approximately 75 times brighter than Earths Sun
Star 3:Color: White Surface temperature: 9000 K Luminosity: more than 10,000 times brighter than Earths SunStar 4:Color: Yellow Surface temperature: 6500 K Luminosity: approximately 1,000 times dimmer than Earths Sun

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
