Homework Help: Physics (quick check)

Posted by Mo on Thursday, October 1, 2009 at 4:42pm.

A football is kicked at ground level with a speed of 20.8m/s at an angle of 23.3 degress to the horizontal. How much later, in seconds, does it hit the ground?

Tf =(-20.8m/s x Sin 23.3)/-9.80m/s^2
=0.839s

this doesn't sound right to me
