  1. Sep 13, 2011 #1
    Hello everyone,
    i am new to this forum so please excuse me if i haven't found the search function. o.k., i am struggling with the following problems. i really don't have cash to get a tutor so i am hoping some of y'all can help a brother out. i am not sure what formulas to use and why. They are pretty similar & are as follows:

    1.AN OBJECT IS THROWN STRAIGHT UP FROM THE GROUND LEVEL WITH A SPEED OF 50M/S. IF g = 10M/S^2 ITS DISTANCE ABOVE GROUND LEVEL 1.0 SECOND LATER IS?



    2. y = 1/2(-10)*1^2 + 50*1



    3. i got 45m
