Question

What is the kinetic energy of a 144 gram baseball moving at a velocity of 38.7 meters per second?

Answer 1

Answer:

The kinetic energy of the baseball is  107.83 J

Explanation:

Given;

mass of the baseball, m = 144 g = 0.144 kg

velocity of the baseball, v = 38.7 m/s

The kinetic energy of the baseball is given by;

K.E = ¹/₂mv²

where;

m is mass of the object

v is speed of the object

K.E = ¹/₂(0.144)(38.7)²

K.E = 107.83 J

Therefore, the kinetic energy of the baseball is  107.83 J
