I got a suggestion from a friend in how to solve this, but I'm not sure if its 100% correct.
The force from the drag was calculated in my previous post to be 5,58 Newton. Since the ball traveled 5 meters, then its:
5,58 N x 5 m = 27,9 joule
E-kinetic = 0,5(m x v2)
So, if I know the...
Not homework, just a "want to know"-question.
Regarding the drag equation, I did not know what to do after I found the force on the ball due to drag. The formula is:
F = 0,5( P x U2 x Cd x A)
P=mass density of air=1,225 kg/m3
U=velocity of the football=31 m/s (Average speed)
Cd=drag...
Hi
First of all, this is not a homework question, but I'm sorry if it's in the wrong sub-forum.
I know that a football (soccer) has been kicked a distance of 5 meters using 0,16 seconds, that would give an average speed of 112,5 km/h, or approx 31 m/s. But since the speed of a football is...
