Answer:
The average force is 1578.94 N.
Explanation:
Given that,
Mass of baseball = 150 g
Speed = 45 m/s
Speed of pitcher = 60 m/s
Time = 9.5 ms
We need to calculate the average force
Using formula of impulse
...(I)
....(II)
From equation (I) and (II)
Where, m = mass of baseball
= final velocity
= Initial velocity
= time
Put the value into the formula
Hence, The average force is 1578.94 N.
