The baseball has a kinetic energy of #2.90 J#

The kinetic energy of the baseball can be ascertained by using the equation below:

Additionally, the kinetic energy will have units of #kgxxm^(2)/s^(2)#, which is the same as Joules, J.

We already have the mass and velocity, and both have the correct units so all we have to do is plug the given values into the equation:

# KE =(0.5)(0.003 kg)(44 m/s)^(2)#
#KE = 2.90 kgxxm^(2)/s^(2)#

#KE = 2.90 J#
