If the acceleration of a particle is constant in magnitude but not in direction,what type of path is followed by the particle?

Two cars $A$ and $B$ have their displacement-time graph as given below. Which car has a greater velocity?

The velocity$-$time graph of a truck is plotted below.
$(a)$ Calculate the magnitude of displacement of the truck in $15$ seconds.
$(b)$ During which part of the journey was the truck decelerating?
$(c)$ Calculate the magnitude of average velocity of the truck.

List two differences in tabular form between speed and velocity. When is a body said to have: $(a)$ uniform velocity and $(b)$ variable velocity? How is the average velocity of a body calculated when its velocity changes at a non-uniform rate?

$A$ body is moving along a circular path of radius $R$. Find the displacement of the body when it completes half a revolution.

Two cars moving in opposite directions cover the same distance $d$ in one hour. If the cars were moving in a north-south direction,what will be their displacement in one hour?
