Question

Write first and third equations of mation.​

Answer 1

The first equation of motion (Vf =Vi + at) deals with final velocity, initial velocity, acceleration and time. We can use the 1st equation of motion to find final velocity, initial velocity, acceleration and time.

The second equation of motion gives the displacement of an object under constant acceleration: x = x 0 + v 0 t + 1 2 a t 2 .

The third equation of motion gives the final velocity of an object under uniform acceleration given the distance traveled and an initial velocity: v 2 = v 0 2 + 2 a d . v^2=v_0^2+2ad. v2=v02+2ad.

Hope it is helpful to you

god keep u happy always

Answer 2

Explanation:

1st equation of motion----- v= u+at

3rd equation of motion ----- v²-u² = 2as

v= final velocity

u = initial velocity

a = acceleration

s= distance
