Can a long out throw to the sidelines with a 12 arc........have more velocity than a ball throw on rope with only a 5' arc, to the same spot? Because that is what we saw on combine footage...........must be a optical illusion of kinematics..........

To figure out the speed of the football we can use the formula for speed which is: v = d/t (where 'v' represents the speed/velocity, 'd' represents the distance and 't' represents the time taken). So in this example v = 18.288m/1.25s, v = 14.6304m/s or if we use significant digits the answer would be 14.6m/s or 52.6km/hr. If we increase the distance to a hail mary which could be 50 yards (45.72 metres) the time taken will also increase, but since the path of the football will have a projectile motion the arc will also increase. The time taken for the football to reach the wide receiver is 2.75 seconds. The speed is: v = d/t, v = 45.72m/2.75s, the speed is v = 16.6255m/s and if we use significant digits, the answer would be 16.6m/s or 59.8km/hr. Speed is scalar because it is just a measurement. Velocity is vector so it is the same as speed except it has a direction.

What we need to know, is at those velocity rates, presuming they are at the max of each prospective player.........who maintaines accuracy while creating speed and velocity.
