Question

A pitching machine is used to pitch two balls. The speed of both balls is 94 km/hr. The mass of one ball is 5 grams, and the mass of the other ball is 50 grams. Since both balls are traveling at the same speed, which of the following is true? Responses The 5-gram ball has more kinetic energy than the 50-gram ball. The 5-gram ball has more kinetic energy than the 50-gram ball. The balls have the same kinetic energy.

A) The balls have the same kinetic energy.

B) The 50-gram ball has more kinetic energy than the 5-gram ball.


C)The 50-gram ball has more kinetic energy than the 5-gram ball.

D) Neither ball has any kinetic energy.

Answer 1

The 50-gram ball has more kinetic energy than the 5-gram ball.

Step-by-step explanation:

The kinetic energy of an object is given by the formula KE = (1/2)mv^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.

In this case, both balls have the same speed, so the kinetic energy of the balls will depend on their mass. The 5-gram ball has a lower mass than the 50-gram ball, so it will have less kinetic energy.

Therefore, the correct response is B) The 50-gram ball has more kinetic energy than the 5-gram ball.
