D. It depends on the speed of the object
Use the following formula to solve: A 700-kg vehicle is traveling at a speed of 6 m/s. How much kinetic energy does it have?
kinetic energy = 1/2 mass x speed2
A. 12,600 J
B. 50,400 J
C. 700 J
kinetic energy = 1/2 mass x speed2
A. 12,600 J
B. 50,400 J
C. 700 J
To find the kinetic energy of the vehicle, we can use the formula:
Kinetic energy = 1/2 * mass * speed^2
Substituting the given values:
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 = 0.5 * 700 kg * 36 m^2/s^2
Kinetic energy = 12,600 kg m^2/s^2
Therefore, the kinetic energy of the vehicle is 12,600 joules.
The correct answer is A. 12,600 J.
Kinetic energy = 1/2 * mass * speed^2
Substituting the given values:
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 = 0.5 * 700 kg * 36 m^2/s^2
Kinetic energy = 12,600 kg m^2/s^2
Therefore, the kinetic energy of the vehicle is 12,600 joules.
The correct answer is A. 12,600 J.
