I believe the answer is C, 3
The kinetic energy of an object of mass m moving with speed v is given by:
![K= \frac{1}{2}mv^2](https://tex.z-dn.net/?f=K%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2%20)
For the bicycle in our problem,
![m=10 kg](https://tex.z-dn.net/?f=m%3D10%20kg)
and
![v=2 m/s](https://tex.z-dn.net/?f=v%3D2%20m%2Fs)
, so the kinetic energy is
Answer:According to the Equation (2), centripetal force is proportional to the square of the speed for an object of given mass M rotating in a given radius R.
Explanation:The Period T. The time T required for one complete revolution is called the period. For. constant speed. v = 2π r T holds.
Answer:
The correct answer should be
