A 2.0-kg ball has a momentum of 25 kg×m/s what is the balls speed

As we know, momentum= mass*velocity  acc. to ques. mass = 2kg  momentum= 25kg-m/s  momentum = mass*velocity (speed)  velocity (speed) = momentum/mass  velocity(speed)=25/2  =12.5m/s

                       Momentum = (mass) x (speed)                         (25 kg-m/s) = (2.0 kg) x (speed)                            Speed = (25 kg-m/s) / (2.0 kg)  =  12.5 m/s
