The velocity-time graph (Fig.) shows the motion of a cyclist. Find $(i)$ its acceleration $(ii)$ its velocity and $(iii)$ the distance covered by the cyclist in $15\,\sec $.

Velocity$-$time graph for the motion of an object in a straight path is a straight line parallel to the time axis.

$(a)$ Identify the nature of motion of the body.

$(b)$ Find the acceleration of the body.

$(c)$ Draw the shape of distance-time graph for this type of motion.

If the displacement-time graph for a particle is parallel to displacement axis, what is the velocity of the particle ?

The velocity-time graph of cars $A$ and $B$ which start from the same place and move along a straight road in the same direction is shown below

Calculate :

$(a)$ the acceleration of car $B$ between $2 \,s$ and $4\, s$.

$(b)$ the time at which both the cars have the same velocity.

$(c)$ the distance travelled by the two cars $A$ and $B$ in $8\, s$

$(d)$ Which of the two cars is ahead after $8\, s$ and by how much ?

An object is moving with uniform speed in a circle of radius $7\, m .$ Calculate the distance and displacement when it completes half the circle. What type does the object possess ?

What can you conclude about the motion of a body depicted by the velocity$-$time graphs $(i),(i i)$ and $(i i i)$ given below
