\large \bf \clubs \:  Given  :-

A cyclist is moving with a velocity of 10m/s towards east .He suddenly applies brake such that a retardation of 2m/s² is produced and Cyclist Finally came to rest

  • Initial Velocity = u = 10 m/s

  • Final Velocity = v = 0 m/s

  • Acceleration = a = - 2m/s²

( ∵ Retardation = - ve of Acceratiom in Value )

----------------------

\large \bf \clubs \:   To  \: Find :-

  • Time Taken by Cyclist to come to Rest

----------------------

\large \bf \clubs \:   Solution :-

Let,

Time Taken by Cyclist = t second.

 \orange{ \bf Applying :  v = u +at}

:\longmapsto0 = 10  + ( - 2) \text{t}

:\longmapsto0 = 10 - 2\text{t}

:\longmapsto2\text{t} = 10

:\longmapsto\text{t} =   \cancel\dfrac{10}{2}

\purple{ \large :\longmapsto  \underline {\boxed{{\bf t = 5 \: second} }}}

Hence,

 \large \underline{ \pink{ \underline{ \pmb{  \frak{ \text{T}ime \:  \text Ta \text ken = 5 \:  \text Second }}}}}

 \Large\red{\mathfrak{  \text{W}hich \:\:is\:\: the\:\: required} }\\ \LARGE \red{\mathfrak{ \text{ A}nswer.}}

----------------------

\large \bf \clubs \: Additional\: Info :-

Three Equations of Motion :

 \large \qquad \boxed{\boxed{\begin{array}{cc} \maltese \:  \: \bf v = u + at \\  \\  \maltese \:  \:  \bf s = ut +  \dfrac{1}{2}a {t}^{2}   \\  \\  \maltese  \:  \:  \bf{v}^{2}  -  {u}^{2}  = 2as\end{array}}}
