This is where the class 9 science chapter 8 NCERT solutions pdf might be of help. Yes, an object moving a certain distance can have zero total displacement. The ball hits the ground with a velocity of 20 meters per second. From the given v-t graph, it can be inferred that the object is. Therefore, the shaded area can be represented as: Area under the velocity-time graph = velocity*time. Since average speed is the total distance traveled in a time frame and velocity is the total displacement in the time frame, the magnitude of average velocity and average speed will be the same when the total distance traveled is equal to the displacement. Therefore, total distance = (3 × 108 m/s) * 300s. Required fields are marked *. Planets like Venus and Mars have more than 95% of carbon dioxide in the air making the existence of life impossible. On the other hand, the distance-time graph of an object in non-uniform motion is a curve. Since a = 0.1 m.s-2, v = 12 m.s-1, u = 0 m.s-1, and t = 120s, the following value for s (distance) can be obtained. This is the minimum displacement.

What was the distance of the spaceship from the ground station? NCERT Solutions for Class 9 Science Chapter 4 Multiple Choice Questions. Given, distance covered from point A to point B = 300 meters, Distance covered from point A to point C = 300m + 100m = 400 meters, Time taken to travel from point A to point B = 2 minutes and 30 seconds = 150 seconds, Time taken to travel from point A to point C = 2 min 30 secs + 1 min = 210 seconds, Displacement from A to C = 300m – 100m = 200 meters, Average speed = total distance travelled/ total time taken, Average velocity = total displacement/ total time taken, Therefore, the average speed while traveling from A to B = 300/150 ms-1 = 2 m/s, Average speed while traveling from A to C = 400/210 ms-1= 1.9 m/s, Average velocity while traveling from A to B =300/150 ms-1= 2 m/s, Average velocity while traveling from A to C =200/210 ms-1= 0.95 m/s.
