An object starting from rest travels $20 \, m$ in the first $2 \, s$ and $160 \, m$ in the next $4 \, s$. What will be the velocity after $7 \, s$ from the start (in $, m/s$)?

An object is moving along a straight line with uniform acceleration. The following table gives the velocity of the object at various instants of time.

Time $(s)$	$0$	$1$	$2$	$3$	$4$	$5$	$6$
Velocity $(m s^{-1})$	$2$	$4$	$6$	$8$	$10$	$12$	$14$

Plot the graph.
From the graph:
$(i)$ Find the velocity of the object at the end of $2.5 \ s$.
$(ii)$ Calculate the acceleration.
$(iii)$ Calculate the distance covered in the last $4 \ s$.

The slope of a velocity-time graph gives:

$(a)$ Define circular motion.
$(b)$ "Uniform circular motion is an accelerated motion". Justify this statement with reason.
$(c)$ An artificial satellite is moving in a circular orbit of radius $42250 \, km$. Calculate its speed if it takes $24 \, h$ to revolve once around the Earth.

Under what condition will the displacement and distance have the same magnitude?

The displacement of a body is proportional to the cube of the time lapsed. The magnitude of the acceleration is
