Use the following formula to solve a 700 KG vehicle is traveling at a speed of 6M/S how much kinetic energy does it have
Kinetic energy equals 1/2 mass times speed2
A. 12,600 J.
B. 50,400 J.
C. 700 J.
To solve for the kinetic energy, we can plug the given values into the formula:
Kinetic energy = 1/2 * mass * speed^2
Mass = 700 kg
Speed = 6 m/s
Kinetic energy = 1/2 * 700 kg * (6 m/s)^2
Kinetic energy = 1/2 * 700 kg * 36 m^2/s^2
Kinetic energy = 18,900 kg m^2/s^2
Therefore, the kinetic energy of the 700 kg vehicle traveling at a speed of 6 m/s is 18,900 J.
The correct answer is not among the options provided.
The correct answer is C. Mass and speed.
To understand why, let's break down each option and explain how it relates to kinetic energy:
A. Color and shape: The color and shape of an object do not directly affect its kinetic energy. Kinetic energy is related to an object's motion, regardless of its color or shape.
B. Temperature and volume: Temperature and volume are not directly related to kinetic energy. Temperature is a measure of the average kinetic energy of the particles within a substance, while volume is a measure of the amount of space the object occupies. However, neither temperature nor volume directly affect an object's intrinsic kinetic energy.
C. Mass and speed: Kinetic energy is directly influenced by both mass and speed. The formula for kinetic energy is KE = 1/2 * m * v^2, where KE represents the kinetic energy, m represents the mass of the object, and v represents its velocity or speed. This formula demonstrates that the kinetic energy of an object increases as both its mass and speed increase.
D. Height and width: Height and width do not directly affect an object's kinetic energy. While height may influence potential energy (energy related to an object's position relative to the ground), it does not impact the intrinsic kinetic energy of the object itself.
Therefore, the correct factors that affect the kinetic energy of an object are its mass and speed (Option C).
