Average acceleration of the baseball:
Explanation:
Since the motion of the baseball is a uniformly accelerated motion, we can use the following suvat equation:
where
u is the initial velocity
v is the final velocity
a is the acceleration
s is the displacement of the object
For the baseball in this problem, we have:
u = 2.2 m/s is the initial velocity
v = 0 is the final velocity (it comes to a stop)
s = 24 mm = 0.024 m is the displacement of the ball while decelerating
Therefore, we can solve for a to find the acceleration:
where the negative sign means the baseball is slowing down.

Answer:
Part a)
Part B)
percentage increase is
%
Explanation:
Part a)
As we know that the beat frequency is
after increasing the tension the beat frequency is decreased and hence the tension in string B will increase
So we have
Part B)
percentage increase in the tension of the string will be given as
now we have
so we have
so we have
percentage increase is
