Answer 1

Hope it helps you in a better way.

Answer 2

First and third equation of motion are as follows-

First equation of motion states the relationship between velocity and time.

The equation is - v = u + a*t. In the equation, v is finally velocity, u is initial velocity, a is acceleration and t is time.

Third equation of motion indicates relationship between distance and velocity.

The equation is - v² = u² + 2aS. In the equation, v is final velocity, u is initial velocity, a is Acceleration and S refers to distance travelled.
