Homework Help: physics repost

Posted by Jon on Thursday, April 3, 2008 at 9:21am.

A player kicks a football with an initial velocity of 3.00 m/s at an angle of 60.0 above the horizontal. What is the horizontal distance traveled by the football?

2(3.00)(cos60)/9.80
(3.00)(cos60)(.530219635)
0.795m
___________________________________
"The looks like a pretty short punt to me: about 2 feet. The correct formula is (horizontal velocity component)* (time of flight). There should be a sin 60 and a v^2 in the answer, besides the factors already there in your first equation."


Ok but I thats the biggest answer choice I have.

A)0.312m
B)0.397m
C)0.673
D)0.795 what I got

I don't understand "The correct formula is (horizontal velocity component)* (time of flight). There should be a sin 60 and a v^2 in the answer, besides the factors already there in your first equation."
