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

d is the answer i came up with

the results is a decrease in air temperature with an increase of altitude.
