A car and semi are travelling down the road at the same speed. They both slow down with the same stopping force. Which statement best explains why the semi needs more distance than the car to stop.
A. The semi is longer.
B. The semi has larger wheels.
C. The semi has more mass.
D. The semi has less mass.
C. The semi has more mass.

An empty truck and a fully loaded truck are next to each other at a traffic light. When the light turns green, the empty truck increases speed more quickly. Why? Use newtons laws
the empty truck has less mass so it has greater acceleration
