Q6 of 59 Page 255

A particle accelerates from rest at a constant rate for some time and attains a constant velocity of 8 ms-1. Afterwards it decelerates with a constant rate and comes to rest. If the total time taken is 4 second, the distance travelled is:

Now, from the given velocity – time graph we can calculate the distance by calculating area under the graph.



Distance Travelled = Area under the graph


=


= 16 m


Hence option B is correct

A car travels 100 km east and then 100 km south. Finally, it comes back to the starting point by the south-east route. Throughout the journey the speed is constant at 60 kmh-1. The average velocity for the whole journey if time taken is 3.3 hours is:

5

The displacement of a body is proportional to the cube of the time lapsed. The magnitude of the acceleration is:

7

A body moves on three quarters of a circle of radius r. The displacement and distance travelled by it are:

8

For the motion on a straight line path with constant acceleration the ratio of the magnitude of the displacement to the distance covered is:
