Answer:
Kinetic energy of the ball, E = 140.04 Joules
Explanation:
It is given that,
Mass of the baseball, m = 0.324 lbs = 0.146 kg
Speed of the baseball, v = 98 mph = 43.80 m/s
We need to find its kinetic energy at the moment before impact. Kinetic energy is given by :
[tex]E=\dfrac{1}{2}\times m\times v^2[/tex]
[tex]E=\dfrac{1}{2}\times 0.146\times (43.80)^2[/tex]
E = 140.04 J
So, the kinetic energy of the baseball is 140.04 Joules. Hence, this is the required solution.
