Estimate the average force that a baseball pitcher's hand exerts on a 0.145-kg baseball as he throws a 40-m/s pitch. assume the pitcher accelerates the ball through a distance of 3.0 m, from behind his body to where the ball is released and ignore the air resistance.

Force, F = 38.66 N

Explanation:

It is given that,

Mass of the baseball, m = 0.145 kg

Initial speed of the baseball, u = 0

Final speed of the baseball, v = 40 m/s

Distance covered, d = 3 m

Let a is the acceleration of the baseball. It can be calculated using the third equation of motion as :

Let F is the average force that a baseball pitcher's hand exerts on a baseball. Using the second equation of motion to find it :

F = 38.66 N

So, the average force a baseball pitcher's hand exerts on a baseball is 38.66 N. Hence, this is the required solution.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
