Answer:
0.4 s
Explanation:
The time that the ball is in the air can be found with the next formula:
where 
is the initial velocity of the ball, in this case:
β is the angle: β = 29.0°
And g is the acceleration of gravity: 
Replacing all the values to find t, we have:
Thus, the ball is 0.4s in the air.
Some scientist believe that the ozone layers of the earth had been weakening and the waters or current changes direct ever 5-7 month.
Collaboration in science is important because if only one scientist does an experiment, and gets a result, he/she could have messed. So this is where collaboration comes in. A few other scientists could try the experiment, and if they get the same answers, the result may be proven correct.
Hope this helped!
