QUESTION: A baseball is hit 1.2 meters above the ground, at an angle of 26 degrees, with an initial speed of 80 m/s.
a. Will it clear a 3.8m fence 120m away from the home-run?
MY PROCESS(But not positive I am doing it correctly)
KNOWN
Vx= 80cos26=71.9 m/s
Vy= 80sin26=35.07 m/s
So I did the problem as if from ground level and tried to find time.(using -10 as my acceleration thankyou Mr Werner)
> 0=35.07+-10t t=3.2x2=7s
*got my time to be 7s
Then I am completely lost on what to do after that. I tried finding the how high the ball is when it is insantaneously at 120m in the x direction but my numbers are so extremely wrong... HELLLP MEEEEEE! please
