Question

why Was the speeding car having greater momentum that the other car? If so why?​

Answer 1

$\huge\color{cyan}\boxed{\colorbox{red}{answer:}}$

Momentum is the mass of an object multiplied by its velocity. A moving truck has more momentum than a car moving at the same speed because the truck has more mass. A fast car can have more momentum than a slow truck. A truck at rest has no momentum at all.
