You throw a baseball with a mass of 0.5 kg. The ball leaves your hand with a speed of 35 m/s. Calculate the kinetic energy. (SHOW ALL WORK)

The kinetic energy of the baseball is 306.25 joules.

Explanation:

SInce the baseball can be considered a particle, that is, that effects from geometry can be neglected, the kinetic energy (), in joules, is entirely translational, whose formula is:

(1)

Where:

- Mass, in kilograms.

- Speed, in meters per second.

If we know that and , then the kinetic energy of the baseball thrown by the player is:

The kinetic energy of the baseball is 306.25 joules.

the body's situation won't change the forces are equal opposit and on the same body

like poles repel so keep pushing north to north and repels funny to see this
