Write true or false for the following statements
Velocity and speed are measured in different units.
False
Can the displacement of a particle be zero when the distance travelled is not zero ?
What kind of motion of a body is represented by the graphs given below ?
What can we conclude about the motion of a body depicted by following velocity$-$time graphs ?
Derive following equations for a uniformly accelerated motion
$(i)$ $v=u+a t$
$(ii)$ $S=u t+1 / 2 a t^{2}$
$(iii)$ $v^{2}-u^{2}=2 a S,$ where symbols have their usual meaning.
A driver of a train travelling at $40\, m s ^{-1}$ applies the breaks as a train enters a station. The train slows down at a rate of $2\, m s ^{-2} .$ The platform is $400\, m$ long. Will the train stop in time ?
