उत्तर
From 0 to 10 sec. i.e O to A motion is accelerating one. From 10 s to 30 sec. scooter is moving with uniform velocity, from 30 s to 50 sec scooter is retarding fromB to c.

Observe the figure and answer the questions.
Sachin and Sameer started on a motorbike from place A, took the turn at B, did a task at C, travelled by the route CD to D and then went on to E. Altogether, they took one hour for this journey.
Find out the actual distance traversed by them and the displacement from A to E. From this, deduce their speed.
What was their velocity from A to E in the direction AE?
Can this velocity be called average velocity?
Explain the following concept in your own words with everyday examples:
Velocity
A body goes from A to B with a velocity of 30 ms-1 and comes back from B to A with a velocity of 20 ms-1. What is the average velocity of the body for the whole journey?
What is the slope of the body when it moves with uniform velocity?
A body moves with an initial velocity of 5ms-1 and accelerates at 2ms -2. Its velocity after 10s is ______.
If final velocity is equal to initial velocity the value of acceleration is ______.
Assertion: An object can have constant speed but the variable velocity
Reason: Speed is a scalar but velocity is a vector.
