Answer:


\large{ \tt{☄ \: EXPLANATION}} :

  • Before solving , You'll have to know - When an object starts from the state of rest , in this case , initial velocity ( u ) = 0

  • Notice that we're provided the time ( t ) in minutes. So , first thing we have to do is convert the minutes into seconds. It would be - Time ( t ) = 5 minutes = 5 × 60 sec = 300 sec [ 1 min = 60 sec ]

  • Here , We're provided - Initial velocity ( u ) = 0 , Final velocity ( v ) = 60 m / s , Time taken ( t ) = 300 seconds & We're asked to find out the acceleration ( a ) & distance covered by the jeep ( s ) .


\large{ \tt{♨ \:LET'S \: START}} :

  • Acceleration is defined as the rate of change of velocity. We know :


\large{ \boxed{ \tt{❁ \: ACCELERATION \: (a) = (FINAL \: VELOCITY(v) - INITIAL \: VELOCITY(u))/(TIME \: TAKEN \: ( \: t \: ))}}}

- Plug the values & then simplify !


\large{ \bf{↬a = (60 - 0)/(300) = (60)/(300) = \boxed{ \bold{ \bf{0.2 \: m {s}^( - 2) }}} }}

  • The acceleration of the jeep is 0.2 m/s²


\large{ \tt{۵ \: AGAIN, \: USING\: SECOND \: EQUATION \: OF \: MOTION}} :


\boxed{ \large{ \bf{✾ \: s = (u + v)/(2) * t}}}

- Plug the values & then simplify !


\large{ \bf{↦s = (0 + 60)/(2) * 300 = \boxed{ \bold{ \bf{9000 \: m}}}}}

  • The distance covered by the jeep is 9000 m .
