Answer:


2.5m/s^(2)

Step-by-step explanation:

Since the distance ,s = 500m

Initial velocity, u = 0m/s

Final velocity, v = 50m/s

We can one of the kinematics equations to find the acceleration.


v^(2) =u^(2) +2as\\50^(2) =0^(2) + 2a(500)\\2500 = 0 + 1000a\\1000a = 2500\\a = (2500)/(1000) \\= 2.5m/s^(2)
