There are 5 houses on a street, $A, B, C, D$ and $E$. For all cases, assume that positions to the right are positive.
$(i)$ Draw a frame of reference with house $A$ as the origin and the positions of houses $B, C, D$ and $E$.
$(ii)$ You live in house $C.$ What is your position relative to house $E$ ?
$(iii)$ What are the positions of houses $A$ and $D$, if house $B$ is taken as the reference point ?
$(ii)$ My house $(C)$ is $20 m$ farther from the house $E$.
$(iii)$ The distance between houses $A$ and $D$ from the house $B$ are $10 m$ and $20 m$ respectively.
A cyclist driving at $36\, km h^{-1}$ stops his cycle in $2\, s$ by the application of brakes. Calculate $(i)$ retardation $(ii)$ distance covered during the application of brakes.
What is the numerical ratio of average velocity to average speed of an object when it is moving along a straight path ?
Prove that if a body is thrown vertically upward, the time of ascent is equal to the time of descent.
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.
An electric train is moving with a velocity of $120\, km h^{-1} .$ How much distance will it corer in $30 \,s$ ?
