a student rides her bicycle down a hill she and the bicycle have a mass of 56 kilograms she is moving at 11 meters per second what is her kinetic energy?
The kinetic energy (KE) of an object is given by the formula:
KE = (1/2) * mass * velocity^2
Here, the mass of the student and the bicycle is given as 56 kilograms and the velocity is given as 11 meters per second.
Plugging in the values, we have:
KE = (1/2) * 56 kg * (11 m/s)^2
= (1/2) * 56 kg * 121 m^2/s^2
= 3088 kg m^2/s^2
Therefore, the kinetic energy of the student and the bicycle is 3088 joules.
