Question

derivation of first second and third equation of motion

Answer 1

HERE IS YOUR ANSWER...
1st equation of motion is v = u+ at

derivation= a= v-u / t
at = v- u
v= u+at

3rd equation of motion
v square = u square + 2as
derivation = average speed of velocity = u+v/2
displacement = v-t
and we know t= u- v/a
s= u+v/ 2 - u-v/ a
s= u square - v square/ 2a
v square = u square - 2as

HOPE THIS IS HELPFUL.....
