Apitcher throws a softball toward home plate. when the ball hits the catcher’s mitt, its horizontal velocity is 32 meters/second. the softball’s velocity goes to 0 meters/second in 0.8 seconds when caught. if the softball has a mass of 0.2 kilograms, what’s the force of the impact? use f = ma, where . the force of the impact is newtons.

Answer
8 Newtons

Explanation
The first step is to calculate the acceleration (a) of the ball.
 
a = (v-u)/t
where a⇒acceleration
           v ⇒final velocity = 0 m/s
           u ⇒initial velocity =32 m/s

∴a = (0 - 32)/0.8
     = -40m/s² 
The acceleration is negative indication the softball was decelerating. 

Now force of impact;

F = ma
where m⇒ mass of the softball in kilogram

F = 0.2×-40
   = -8

But force can not be negative,
So, impact force =8 Newtons

If there was no gravity then their would be no downword force on the football to have it return the the grownd, and if there was no friction (mainly air friction) then there would be no opposing force the stop the ball from moving through the air allowing the ball to travle ∞.
