A baseball has a mass of about 145 grams.
A softball has a mass of about 185 grams.
A pitcher throws the baseball and then throws the softball. For both pitches, the pitcher gives the two balls the
same amount of kinetic energy. Will the balls be traveling at the same speed or different speeds, and how do you
know?

The ball with smaller mass (baseball) will travel faster when he pitcher gives the two balls the same amount of kinetic energy.

The given parameters:

  • Mass of the baseball, m = 145 g = 0.145 kg
  • Mass of the softball, M = 185 g = 0.185 kg

What is kinetic energy?

  • Kinetic energy of an object is the energy possessed by the object due to its motion.

The kinetic energy of an object in motion is calculated as follows;

[tex]K.E = \frac{1}{2} mv^2[/tex]

The speed of each ball with respect to their masses is calculated as follows;

[tex]K.E = \frac{1}{2} mv^2\\\\2K.E = mv^2\\\\v^2 = \frac{2K.E}{m} \\\\v = \sqrt{\frac{2K.E}{m} } \\\\[/tex]

Thus, the ball with smaller mass (baseball) will travel faster when he pitcher gives the two balls the same amount of kinetic energy.
