 change in velocity as well ok. Then we will again come back to solving numerical of constant velocity, but let us talk about the entire graphic analysis today itself. Now acceleration is acceleration represents rate at which velocity is changing. So, more is a change in velocity. So, the average change in velocity which is V 2 minus V 1 you can say divided by delta t it is a vector quantity. So, this acceleration right can do not change it direction can change example circle will be tends to 0 0 0 how do you say 0 it is 6 meter per second that divided by 5. So, minus 6 by 5 acceleration what is extremely important it reaches here the utmost time it is taking 6 seconds. So, I know it is simply like this. So, your initial velocity is what in terms of i cap and j cap 3 j this is initial upwards yes or no your final velocity. So, difference in velocity u 2 minus u 1 is 3 i minus 3 j. So, acceleration is the average speed root of 3 square plus 3 square divided by square is a minus u. So, this is u. So, minus u so diagonal again just change it.
