Which of the following figures (Fig.) represents uniform motion of a moving object correctly?

$A$ motorbike running at a speed of $90\, km h^{-1}$ slows down to $18\, km h^{-1}$ in $2.5\, s$. Calculate:
$(i)$ Acceleration
$(ii)$ Distance covered during the deceleration

$A$ ball is thrown vertically upwards. What is its momentum at the highest point?

$A$ stone is thrown vertically upwards with a velocity of $40 \, m s^{-1}$ and is caught back. (Taking $g = 10 \, m s^{-2}$) Calculate the maximum height reached by the stone. What is the net displacement and total distance covered by the stone?

$A$ circular cycle track has a circumference of $314 \ m$ with $AB$ as one of its diameters. $A$ cyclist travels from $A$ to $B$ along the circular path with a velocity of constant magnitude $15.7 \ m s^{-1}$. Find the:
$(a)$ distance moved by the cyclist.
$(b)$ displacement of the cyclist,if $AB$ represents the north-south direction.
$(c)$ the average velocity of the cyclist.

What is the shape of the path followed by a projectile?
