Question

A baseball has a mass of about 145 grams.

Answer 1

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;

$K.E = \frac{1}{2} mv^2$

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

$K.E = \frac{1}{2} mv^2\\\\2K.E = mv^2\\\\v^2 = \frac{2K.E}{m} \\\\v = \sqrt{\frac{2K.E}{m} }$

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