The edge of a flying disc with a radius of 0.13 m spins with a tangential speed of 3.3 m/s. the centripetal acceleration of the edge of the disc is m/s2

Explanation:

The centripetal acceleration is defined as the square of the tangential velocity between the radius.

In this case we know that the radius r is

The speed v is:

Then we use these values to find the centripetal acceleration.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
