A student rides her bicycle down a hill. Together, she and the bicycle have a mass of 56 kilograms. She is moving at 11 meters per second. What is her kinetic energy?(1 point)%0D%0AResponses%0D%0A%0D%0A6,776 J%0D%0A6,776 J%0D%0A%0D%0A13,552 J%0D%0A13,552 J%0D%0A%0D%0A17,248 J%0D%0A17,248 J%0D%0A%0D%0A3,388 J
To calculate the kinetic energy, we use the formula:
Kinetic energy = 1/2 * mass * velocity^2
Plugging in the values given:
Kinetic energy = 1/2 * 56 kg * (11 m/s)^2
= 1/2 * 56 kg * 121 m^2/s^2
= 6,876 J
Therefore, the correct answer is 6,876 J.
To calculate the kinetic energy of an object, you can use the following formula:
Kinetic Energy = 0.5 * mass * velocity^2
Given that the mass of the student and the bicycle is 56 kilograms and the velocity is 11 meters per second, we can plug in these values and calculate the kinetic energy:
Kinetic Energy = 0.5 * 56 kg * (11 m/s)^2
= 0.5 * 56 kg * 121 m^2/s^2
= 3388 J
Therefore, the kinetic energy of the student and the bicycle is 3388 J.
To calculate the kinetic energy of the student and her bicycle, we can use the formula:
Kinetic energy = 1/2 * mass * velocity^2
Given:
Mass of the student and bicycle = 56 kg
Velocity = 11 m/s
Plug in the values into the formula:
Kinetic energy = 1/2 * 56 * (11)^2
Simplify:
Kinetic energy = 1/2 * 56 * 121
= 2816 J
Therefore, the kinetic energy of the student and her bicycle is 2816 J.
