Answer:

The kinetic energy of the baseball is 306.25 joules.

Step-by-step explanation:

SInce the baseball can be considered a particle, that is, that effects from geometry can be neglected, the kinetic energy (
K), in joules, is entirely translational, whose formula is:


K = (1)/(2)\cdot m\cdot v^(2) (1)

Where:


m - Mass, in kilograms.


v - Speed, in meters per second.

If we know that
m = 0.5\,kg and
v = 35\,(m)/(s), then the kinetic energy of the baseball thrown by the player is:


K = (1)/(2)\cdot m \cdot v^(2)


K = 306.25\,J

The kinetic energy of the baseball is 306.25 joules.
