Here, we are required to justify the reason why a cotton ball may not be used as a baseball in a baseball game.
- This is due to the relatively small mass of a cotton ball as this consequently, affects the force on the ball when it's in play. As we know, force is a rate of change of momentum with time.
- From Newton's laws, Newton's second law of motion to be particular, the rate of change of momentum with time is directly proportional to the force applied on the object.
i.e F = (mv - mu)/t.
The law above can also be written as, F = m × a
Where
m = mass,
a = acceleration.
- In either case, the mass (i.e quantity of matter present in it) of the cotton ball is relatively small and therefore would not be sufficient to produce the force required during passing during the baseball game.
Consequently, the change in
momentum is low and so is
the force.
Ultimately, the cotton ball is not a good fit as a baseball for a baseball game.
