PLEASE HELPPPPP

Answer 1

The only graph that accurately depict the given motion is graph D.

The given parameters;

• initial position of the man = 0

• direction of the man's first displacement = backward
• time of first motion, t₁ = 6 seconds
• velocity of this first displacement = v₁
• time without any motion (zero movement) = 6 seconds
• direction of the second displacement = forward
• velocity of second displacement = 2v₁

Let the acceleration of the first displacement = a

Acceleration of the second displacement = 2a

From the given graphs we can eliminate every graph without initial decrease or motion towards the negative direction.

The only options with initial motion towards the negative direction are;

• graph B, and

• graph D.

The difference between graph B and D;

• in graph B there is a uniform motion for 6 seconds

• in graph D there is no motion for 6 seconds (this is obvious as the line fall directly on top of the horizontal axis maintaining a value of zero for 6 seconds).

Thus, the only graph that accurately depict the given motion is graph D.
