QUESTION IN ATTACHEMENT(KINEMATICS GRAPH)

Answer 1

Answer:

I and III only

Explanation:

• acceleration is the slope of v-t graph

       so the acceleration of car X is greater as slope is greater.

       slope of car X = 40/20 = 2m/s²

       slope of car Y = 20/40 = 0.5m/s²

• distance is given by the area under v-t graph

       area of car X= 1/2 × 40 × 20 = 400m

       area of car Y= 1/2 × 20 × 40 = 400m

      so as area of car X and Y are same so they travel the same distance   but with different acceleration.
