Answer 1

QUESTION:-

If a car has uniform accerleration of 5m/s what is the velocity after 5 second if car started from rest.​

EXPLANATION:-

$\setlength{\unitlength}{2mm}\begin{picture}(0,0)\thicklines\put(0,0){\line(3,0){3cm}}\multiput(1,0)(1,0){14}{\qbezier(0,0)(-0.4,-0.4)(-0.9,-0.9)}\put(4,0){\line(0,3){0.6cm}}\put(10,0){\line(0,3){0.6cm}}\put(4,3){\line(3,0){1.2cm}}\put(6,1){ \sf CAR }\put(2,5){ \sf\xrightarrow{Acceleration=5 m/s} }\put(-3,1){ \xrightarrow{\sf velocity=?\quad} }\end{picture}$

So here velocity is to be calculated:-

Using the formula of acc. =$_{\boxed{\boxed{\pink{\underline{\green{\mathscr {_ _\frac{v-u}{t}}}} }} }}}$

Where v=Final velocity

u=initial velocity

t=time

So here acc=5 m/s

Initial velocity=0   {As the body starts from rest}

So let's put the data in the formula to calculate the velocity

$==>a=\frac{v-u}{t}\\\\==>5=\frac{v-0}{5}\\\\==>25=v-0\\\\==>v=25$

Hence the final velocity is 25 m/s
