please give me the answer
who will me correct answer i will give 20 thanks​

Answer 1

→Answer :

Here given data are

Initial velocity = 8 m/s = u

Last velocity = 0 m/s ( Because it stops )=v

Time = 4 seconds

Formula for acceleration = v - u/t

= 0 - 8 /4

=-8 / 4

= - 2 m/second ^2

Here - sign indicates that its speed is decreasing…
