A 58-kg boy swings a baseball bat, which causes a 0.140-kg baseball to move toward 3rd base with a velocity of 38.0 m/s. Calculate the kinetic energy of the baseball (rounding your answer to the integer).

Explanation:

Kinetic energy can be found using the following formula:

The mass of the baseball is 0.140 kilograms and the velocity is 38.0 meters per second.

Substitute the values into the formula.

First, evaluate the exponent.

Multiply the two numbers in parentheses together.

Multiply the fraction by the number, or divide the number by 2.

Round to the nearest whole number. The 0 in the tenth place tells us we can leave the number as is.

1 kg*m²/s² is equal to 1 Joule. Therefore, our answer of 101 kg*m²/s² is equal to 101 Joules (J).

The kinetic energy of the baseball is about 101 Joules.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
