Respuesta :

1134 kgm/s is the momentum of the dog weighing 18 kg runs into a park at a velocity of 63 m/s.

Formula to calculate momentum:

M = mv,

Where: M = Momentum

            m = Mass

             v = Velocity

let given,

mass m =  18 kg

velocity v = 63 m/s

substitute the values in above equation

Momentum, M =  (18×63)

Momentum, M = 1134 kgm/s

Hence, the momentum of the dog is 1134 kgm/s.
