A man steps out of an airplane at 10,000 meters altitude.  He falls 
freely through the air, with no air resistance.  


   1. Write an equation for his velocity as a function of time:

    
         v(t)  =  



   2. Write an equation for his height as a function of time:


         y(t)  = 





   3. Fill in the spaces below for times 1, 2, and 3 seconds.
