Question

The formula for calculating kinetic energy is K = 1/2mv² for which m represents mass and v represents velocity solve this formula.

A) True
B) False

Answer 1

The formula K = 1/2mv² correctly represents the calculation for kinetic energy, where mass and velocity are known, making the answer to the question True.

Step-by-step explanation:

The formula for calculating kinetic energy is indeed K = 1/2mv², where m represents mass and v represents velocity. This formula is used to solve for an object's kinetic energy when both the mass (m) and the velocity (v) are known quantities. To obtain a correct solution, velocity must be in the SI unit of meters per second (m/s), and mass must be in kilograms (kg). For example, the kinetic energy (K.E.) of a 1000 kg car moving at 20 m/s would be calculated as K.E. = 1/2 * 1000 kg * (20 m/s)² = 200,000 Joules (J). So the answer to the question is A) True.

Answer 2

The given statement “The formula for calculating kinetic energy is K = 1/2mv² for which m represents mass and v represents velocity solve this formula.” is false because the given formula
`\(K = (1)/(2)mv^2\)` is accurate for calculating kinetic energy, representing the relationship between mass (m) and velocity (v). The answer "False" may stem from a misinterpretation of the question or a typographical error, as the formula itself is correct.

Step-by-step explanation:

The formula provided,
`\(K = (1)/(2)mv^2\)`, is indeed the formula for calculating kinetic energy. The correct representation is
`\(K = (1)/(2) * m * v^2\),` where (m) represents the mass of an object and (v) represents its velocity.

This formula is derived from the classical mechanics principle that the kinetic energy of an object is proportional to the square of its velocity. Therefore, the given formula accurately represents the relationship between kinetic energy, mass, and velocity.

It's important to note that the question asked whether the statement is true or false. The correct response is "False" because the formula is accurate for calculating kinetic energy, not false. The misunderstanding may arise from a misinterpretation of the question or a typographical error. It's crucial to pay close attention to the details of the question to provide an accurate answer. In scientific contexts, precision in notation and interpretation is essential to avoid misconceptions.
