To determine which truck has more momentum, we need to consider both mass and velocity. Momentum is calculated as the product of mass and velocity (momentum = mass × velocity). If the large truck has a significantly greater mass than the small truck, even at 30 miles per hour, it is likely to have more momentum than the smaller truck moving at a different speed. Without knowing the speed of the small truck, we cannot make a definitive comparison.

KE = 1/2 mass *velocity squared A direct relationship. More mass, and a truck has more mass, and the more kinetic energy if velocities are held equal.
