Question

A car and a truck have the same linear momentum. Which one will have more speed and why?

Answer 1

MOMENTUM

Momentum is defined as the quantity of motion in a body.

Momentum is the product of mass and velocity P=mv

Momentum is directly proportional to mass and velocity, greater the mass of the body greater will be its momentum.

But there is inverse relation between mass and velocity of a body as shown by the equation m=p/v

It is known that truck has more mass than car so velocity of truck will be less than the car while momentum remains constant.
