Answer:
The paintball ball launcher
Explanation:
The average speed of a paintball ball(vo) is approximately 90m/sec
and if the average speed of a ball pitcher in baseball (v1) is 150km/h
, which is equivalent to (150km/h*1000m/km*h/3600sec) = 41.66m/sec therefore the flight time of each mobile must be found to determine which one falls to the ground first
finally you can see that the shortest flight time is from the paintball ball launcher, therefore it will fall to the ground first
Note: Since the launch conditions must be the same for both, except the speed, it is placed 15º as an average value, but it can be any angle as long as it is the same for both

As the headwind comes at the head of the plane, therefore 50 mph headwind slows the plane down.
Thus actual speed of plane with headwind,
Now using the formula ,
Hence plane will take time to complete the distance 1250 mile in 2.5 hours
In SI units with dry air at 20*C (68*F), the speed of sound c is 343 meters per second (m/s).
The answers is 343 meters per second:
