Question

please answer the (b) question​

Answer 1

Initial Velocity of car 'u'= 4

Final Velocity 'v' = 20

Time 't' = 4

Acceleration 'A'= ( v - u ) / t

= ( 20 - 4 ) / 4

=16 / 4

= 4

Answer 2

Answer:

Initial Velocity of car 'u'= 4

Final Velocity 'v' = 20

Time 't' = 4

Acceleration 'A'= ( v - u ) / t

= ( 20 - 4 ) / 4

=16 / 4

= 4

\begin{gathered}\boxedInitial \: Velocity \: of \: car \: 'u'= 4 \\ Final \: Velocity\: 'v' = 20\\ Time 't' = 4\\ Acceleration 'A'= ( v - u ) / t\\ = ( 20 - 4 ) / 4\\ =16 / 4 = 4ms^2\\\end{gathered}
