Answer:
Explanation:
The acceleration of an object is the rate of change of velocity. The mathematical expression for the acceleration of an object is given by :
Where
v and u are final and initial velocities
t is time
or we can write acceleration as :
Hence, this is the required solution.
It’s not arrested because if you look closer it’s plug walk I don’t even understand how it talk tho

Answer:
131.09828 Joules
Explanation:
u = Initial velocity of the ball = 0
v = Final velocity of the ball when the batter makes contact with the ball= 42.91 m/s
m = Mass of the baseball = 0.1424 kg
Kinetic energy
The kinetic energy the ball has is 131.09828 Joules
