When will you say a body is in $(i)$ uniform acceleration ? $(ii)$ nonuniform acceleration ?
Joseph jogs from one end $A$ to the other end $B$ of a straight $300\, m$ road in $2\, min$ $30\, sec$ and then turns around and jogs $100 \,m$ back to point $C$ in another $1\, min$. What are Joseph's average speeds and velocities in jogging from $A$ to $C$ ?
A bus starting from rest moves with a uniform acceleration of $0.1\, m s^{-2}$ for $2\,min$. Find $(a)$ the speed acquired, $(b)$ the distance travelled.
An object has moved through a distance. Can it have zero displacement? If yes, support your answer with an example.
A stone is thrown in a vertically upward direction with a velocity of $5\, m s^{-1}$. If the acceleration of the stone during its motion is $10\, m s^{-2}$ in the downward direction, what will be the height attained by the stone and how much time will it take to reach there ?
