Without the wheels, a bicycle frame has a mass of 6.71 kg. each of the wheels can be roughly modeled as a uniform solid disk with a mass of 0.820 kg and a radius of 0.343 m. find the kinetic energy of the whole bicycle when it is moving forward at 3.22 m/s.

43.311 J

Explanation:

Given

mass of frame

mass of  wheel

radius of wheel

v=3.22 m/s

Moment of inertia of each wheel\left ( I\right )=\frac{1}{2}mr^2[/tex]

kinetic Energy of whole cycle=Kinetic energy of wheels and frame+rotational energy of Wheels

K.E.=39.037+4.274=43.311J

answer: 31, 5556. 952 seconds
