The average force of a baseball is 18.9 N. Its mass is 0.145 kg.
Find the acceleration.

Work Shown:

Force = Mass*Acceleration

F = m*a

18.9 = 0.145*a

0.145*a = 18.9

a = 18.9/0.145

a = 130.344827586207

a = 130

I rounded to three sig figs because the given values are accurate to three sig figs. The units of acceleration are m/s^2.

Saying 130 m/s^2 means that every second, the baseball's velocity is increasing by 130 m/s. You can think of the velocities taking on multiples of 130 like so {130, 260, 390, 520, ...} though we're dealing with a continuous set of values rather than discrete set.

The acceleration is really large because the ball is going very fast in a short amount of time. For example, fast ball pitches can be 100 miles per hour, and the ball goes from 0 to 100 in a very short amount of time (less than 1 second).

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
