1. calculate the momentum of a 50kg carton that slides across an icy surface at 4 m/s.

The momentum of the carton, P = 200 kg • m/s

Explanation:

Given that,

Mass of the object, M = 5 Kg

Velocity of the object, V  = 1.2 m/s

The product of the mass and velocity of the body is defined as momentum. It is denoted by 'P'.

                                     P = MV

Substituting the values in the above equation

                                     P = 50 Kg x 4 m/s

                                        = 200 kg • m/s

Hence, the momentum of the object is P = 200 kg • m/s
