A horizontal force of 350 NN is exerted on a 2.0-kgkg ball as it rotates (at arm's length) uniformly in a horizontal circle of radius 0.90 mm. Part A Calculate the speed of the ball. Express your answer to two significant figures and include the appropriate units.

The value is  

Explanation:

From the question we are told that

    The horizontal force is  

    The mass of the ball is  

     The radius is    

Generally the speed of the ball is mathematically evaluated from  the formula for  centripetal force as

=>      

=>      

=>      

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.
