Homework Help: Physics

Posted by Sam on Thursday, October 7, 2010 at 4:37pm.

I have a golf ballthat is hit for 0.20s at an angle to the horizontal and it hits the ground some distance away. Initial speed is 30m/s and angle of projection is 35. Calculate the time between when the ball was hit and when it first touched down.

I think it should be 30m/s cos 35/9.8.

If not correct please let me know what formula to use.
