how long does it take a football, with an initial velocity of 30 m/s at 30 degrees up from the horizontal, to reach the top of its flight?
Δy= ½ (Vf + Vo) t
The Attempt at a Solution
I know that Vf= 0 m/s here because when it reaches the highest point, it stops for a split second. I also know that the horizontal component is 30sin(30), which equals 15. I then plugged it into the equation above to get
15= ½ (0+30)t → 15= 15t → t= 1 second.
Is this process correct?
