a baseball pitcher throws a baseball with a speed of 38m/s. estimate the average acceleration of the ball during the throwing motion,. in throwing the baseball, the pitcher accelerates the ball through a displacement of about 3.5 m from behind the body to hthe point where it is released.
please and thank you
a = [v(f)^2 –v(i)^2]/2•s = v(f)^2/2•s= =38^2/2•3.5 = 206.3 m/s^2
