Astreet ball whose mass is 2.0 kg is rolling at a rate of 2.8 m/so what is its momentum

Given that

mass of ball ( m) = 2 Kg,

velocity (v) = 2.8 m/s ,

Momentum of ball = ?

   We know that "Momentum is simply means, mass in motion

                 Mathematically,                        

                                  momentum (p) = m.v

                                                           = 2× 2.8

                                                           = 5.6 Kg.m/s

                                                =

the answer is b ) square root of 5
