Question

Prove second equation of motion. Class 9th.

Answer 1

Second Equation of motion.

Good question,

Here is your perfect answer!

S = (u+v)/2 * t

Displacement = Av velocity * time

Since v = u + at

=) S = (u + u +at) /2 * t

=) S = (2u + at) /2 * t

=) S = 2ut/2 + at²/2

=) S = ut + at²/2.

Here S is displacement, u initial velocity, a fr acceleration and t is time taken.

Answer 2

ANSWER

SECOND EQUATION OF MOTION

S=UT+1/2at^2

SEE IN PICTURE.
