4. A baseball is pitched with a speed of 35 m/s. If the baseball has a mass of 0.146 kg, what is its
Kinetic energy? (35 m/s = 78 mph just FYI - use the m/s)

Respuesta :

Answer: 89 J

Explanation:

The kinetic energy of the baseball with the given mass and speed is 89.425 Joules.

What is the Kinetic energy of the baseball?

Kinetic energy is simply a form of energy a particle or object possesses due to its motion.

It is expressed as;

K = (1/2)mv²

Where m is mass of the object and v is its velocity.

Given the data in the question;

  • Mass of the baseball m = 0.146kg
  • Velocity v = 35m/s
  • Kinetic energy of the baseball K = ?

K = (1/2)mv²

K = (1/2) × 0.146kg × (35m/s)²

K = 0.5 × 0.146kg × 1225m²/s²

K = 89.425kgm²/s²

K = 89.425J

The kinetic energy of the baseball with the given mass and speed is 89.425 Joules.
