The acceleration of a baseball pitcher's hand as he delivers a pitch is extreme. For a professional player, this acceleration phase lasts only 50 ms, during which the ball's speed increases from 0 to about 90 mph, or 40 m/s.
What is the force of the pitcher's hand on the 0.145 kg ball during this acceleration phase?
Express your answer with the appropriate units.

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...

Major League Baseball now records information about every pitch thrown in every game of every season. Statistician Jim Albert compiled data about every pitch thrown by 20 starting pitchers during the 2009 MLB season. The data set included the type of pitch thrown (curveball, changeup, slider, etc.) as well as the speed of the ball as it left the pitcher's hand. A histogram of speeds for all 30,740 four-seam fastballs thrown by these pitchers during the 2009 season is shown...

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.

A batter swings at a baseball (mass 0.145 kg) that is moving horizontally toward him at a speed of 40.0 m/s. He hits a line drive with the ball moving away from him horizontally at 50.0 m/s just after it leaves the bat.
