Question

a waterwheel built in Hamah, Syria, has a radius of 20 m . If the tangential velocity at the wheels edge is 7.85 m/s , what is the centripetal acceleration of the wheel?

Answer 1

3.08m/s²

Step-by-step explanation:

Given parameters:

Radius = 20m

Tangential velocity = 7.85m/s

Unknown:

Centripetal acceleration = ?

Solution:

Centripetal acceleration is the acceleration of a body along a circular path.

it is mathematically given as;

a =
`(v^(2) )/(r)`

v is the tangential velocity

r is the radius

a =
`(7.85^(2) )/(20)` = 3.08m/s²
