A football is kicked with an initial velocity of 42 ft/sec at an angle of 35 degrees with the horizontal. How far has the football traveled horizontally after 0.5 sec? round to nearest tenth.
Could someone explain this please?
I don't know, I just followed an example in my book
Let me edit your work:
so this is the equation of the horizontal component of the football. At time 1/2 second, put that in for t, and you have the horizontal distance.
The rest of your work is not related.
