Question

38.
Use this for the next two questions: You have four vehicles, all driving at the same velocity
side-by-side on a four-lane highway. They are a fully-loaded truck, an empty truck, a midsize
van, and a small car.
Which one has the MOST momentum?
a. the fully-loaded truck
c. the midsize van
b. the empty truck
d. the small car
39.
If all the vehicles brake at the same time because there is a collision ahead, which one will come
to a complete stop FIRST?
a. the fully-loaded truck
c. the midsize van
b. the empty truck
d. the small car​

Answer 1

Answer:

38) d)The small car has the more momentum

39) a)The fully loaded truck stops first

Explanation:

38) d) The small car has more momentum because its weight is less compared to the other vehicles.

I.e. weight(gravitational pull) is related with friction.

39) a) The fully loaded truck stops first because its weight is more , thereby resulting in more friction.

Therefore , more friction = Stops first
