Question

Figure shows the distance time(x-t) graph of the motion of a car It follows from the graph that the car is :-

• A. At rest
• B. In uniform motion
• C. Retarded
• D. Accelerating

Answer 1

Answer: (D)

Accelerating

Slope of the curve in displacement-time graph gives the instantaneous velocity of the car.

According to the graph given, the slope of the curve is positive and increasing with time.

$⟹$ The velocity of the car is increasing with time in positive direction, thus the car is accelerating.
