Achild rides a bicycle in a circular path with a radius of 2.0 m. the tangential speed of the bicycle is 2.0 m/s. the combined mass of the bicycle and the child is 43 kg. what is the magnitude of the centripetal force on the bicycle?

In a uniform circular motion, the centripetal force is given by

where
m is the mass of the system
v is the tangential speed
r is the radius of the orbit

By plugging the numbers given by the problem into the equation, we find the magnitude of the centripetal force:

The characteristics of groundwater is said to be: are weak turbiditya constant temperaturechemical composition and almost overall absence of oxygen.

The center is basically the heart of it
