Imagine a heavy van that is moving at a speed of 80 kph and a motorcycle moving at a speed of 80
kph. Which of these two vehicles is harder to stop?
A.
A moving heavy van is harder to stop than a motorcycle moving at the same speed because of its
mass, this means that the van has a greater momentum than the motorcycle.
B. A moving motorcycle is harder to stop than a heavy van moving at the same speed because of its
mass, this means that the motorcycle has a greater momentum than the van.
C. A moving heavy van and a motorcycle stop at the same time because they have the same speed
of 80 kph.
D. None of the above​
