A flywheel has a radius of 20. 0cm. What is the speed of a point on the edge of the flywheel if it experiences a centripetal acceleration of 900.0cm/s 2 ?

The speed of a point on the edge of  the flywheel is 134.16cm/s

The formula for calculating the centripetal acceleration of the flywheel is expressed as:

where;

v is the speed of the flywheel

r is the radius of the wheel

Given the following parameters

r = 20.0cm

a = 900cm/s²

Substituting the given parameters into the formula above;

Hence the speed of a point on the edge of  the flywheel is 134.16cm/s

Given that,

The radius of a flywheel, r = 20 cm = 0.2 m

The centripetal acceleration experienced on the edge of the flywheel = 900 cm/s² = 9 m/s²

To find,

The speed of a point on the edge.

Solution,

The formula for the centripetal acceleration is given by :

Hence, the required speed is 1.34 m/s
