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) Responses
6,776 J
17,248 J
3,388 J
13,552 J
To calculate the kinetic energy, we can use the formula:
Kinetic Energy = 1/2 * mass * velocity^2
Given that the mass of the student and bicycle combined is 56 kilograms and the velocity is 11 meters per second, we can plug in these values:
Kinetic Energy = 1/2 * 56 kg * (11 m/s)^2
Calculating this expression gives us:
Kinetic Energy = 1/2 * 56 kg * 121 m^2/s^2
Kinetic Energy = 3388 J
Therefore, the kinetic energy of the student and bicycle is 3,388 J.
