Momentum, often denoted as p, is the product of mass and velocity defined by p=mv where m is mass and v is velocity.
The change in momentum is described by where f and i denote final and initial states respectively. As the lorry comes to a halt, its final speed is zero. By substituting the provided values, we find that
According to the principle of energy conservation, the engine's work in moving the scooter is converted into the scooter's kinetic energy, represented as:
