The fastest pitch recorded in baseball was 105.1 MPH (46.98 m/s) by Aroldis Chapman. Assuming the baseball had a mass of 0.145 kg, what was the impulse he imparted on the baseball?
If one was to catch a baseball moving at such a speed with their barehand (assume the catch takes place over a time interval of 0.020 seconds), what force would the baseball impart onto the hand? If hand bones can break when under ~110 Newtons of force, can one safely catch such a ball?
please answer both of these questions and their parts as they are related
we know that,
Change in momentum(P) = impulse imparted(I)
m(v-u) = F*t
m= 0.145 kg
When the ball was first thrown,
u = 0, v = 46.98 m/s,
I = m(v-u)
I = 0.145*(46.98 - 0)
I = 6.8121 N-s
Now again,
u = 46.98 m/s, v = 0 m/s,
I = m(v-u)
F*0.02 = 0.145*(0 - 46.98)
F = -340.605 N
-ve only tells the direction
If the ball is caught in the above specified time period catching it would be fatal,
One other way to safely catch the ball is to take more time to catch the ball, i.e, pull your hands backwards as you catch the ball

The record for the fastest baseball pitch is currently 105.1 mph (46.98 m/s). If the mass of a baseball is 145 g, calculate the wavelength of the baseball for this pitch.
In September of 2010 Aroldis Chapman threw what may be the fastest baseball pitch ever recorded at 105 mi/h (47 m/s). Part A What would the observed frequency of microwaves reflected from the ball be if the source frequency were 10.775 GHz? Part B What would be the beat frequency between the source frequency and the observed frequency?
The fastest pitched baseball was measured at 46 m/s . A baseball has a mass of 148 g . A. If the pitcher exerted his force (assumed to be horizontal and constant) over a distance of 1.1 m , what force did he produce on the ball during this record-setting pitch? B. Make free-body diagram of the ball during the pitch. C. Make free-body diagram of the ball just after it has left the pitcher's hand.
