2.Motion in Straight Line

easy

A body $A$ moves with a uniform acceleration $a$ and zero initial velocity. Another body $B$, starts from the same point moves in the same direction with a constant velocity $v$. The two bodies meet after a time $t$. The value of $t$ is

A$\frac{{2v}}{a}$

B$\frac{v}{a}$

C$\frac{v}{{2a}}$

D$\sqrt {\frac{v}{{2a}}} $

Solution

(a)$\frac{1}{2}a{t^2} = vt \Rightarrow t = \frac{{2v}}{a}$

A student is standing at a distance of $50\,metres$ from the bus. As soon as the bus begins its motion with an acceleration of $1\,ms^{-2}$, the student starts running towards the bus with a uniform velocity $u$. Assuming the motion to be along a straight road, the minimum value of $u$, so that the student is able to catch the bus is………$ms^{-1}$
