A body rises vertically up to height of 125 m in 5 s and then comes back at the point of projection. Find: (i) The total distance travelled, (ii) the displacement (iii) the average speed (iv) the average velocity of the body.​

Answer»

Explanation:

Total distance=250m(125+125)

Total displacement=0(because displacement is length between initial POINT and FINAL point. Here initial point and final point. So displacement is 0.)

Average speed=Total distance÷total TIME taken

=250÷10=25meter PER second

Average velocity=Total displacement÷total time taken

=0÷10=0
