please mark me as the brainliest

Step-by-step explanation:

Answer. Acceleration is defined as the time rate of change in velocity,. So, a=(25-0)/30=5/6 metre per second square.

Thank you

Answer 2

Answer:

WKT,

initial position,u = 0

final position , v = 25 m/s

time, t =30 sec

acceleration , a =v-u/t

a = 25-0/30

= 0.83...m/s -1
