There are two main types of friction, static friction and kinetic friction. Static friction operates between
Answer:

Explanation:
The centripetal acceleration of the child, which is moving by uniform circular motion, is given by

where
v = 5 m/s is the tangential speed of the child
r = 1.2 m is the radius of the circular path
Substituting the numbers into the equation, we find

Light travels approximately 186,000 miles per second in empty space.
Then, if you do the math, it goes 5.88 Trillion miles per year.
