Achild riding mary go round complete one revolution every 8.04 s the child standing 4.17 m from the center of marygoround what is the magnitude of centripetal acceleration of child ?

The magnitude of the child's centripetal acceleration is 2.53

Explanation:

Centripetal acceleration is calculated with the following formula:

= Centripetal acceleration ()

w= speed angular ()

r= radius of the curve(m)

Calculation of the angular velocity of the child

equation (1)

, then, in the equation(1):

Calculation of the child's centripetal acceleration

We replaced and in the equation (1)

The magnitude of the child's centripetal acceleration is

answer

the arrows to the right of earth should point up.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
