A car goes from rest to a speed of 25 m/s in 10 seconds. What is the car's average acceleration in m/s2?

2.5m/s^2

Explanation:

to answer this question the best method would be to use SUVAT equations (attached)

here we have:

U= 0ms

v=25ms

t=10sec

a=?

the best equation to use in this instance is

v = u + at

substitute in the known values:

25=a10

25/10=a

2.5m/s^2 =a

i think the answer would be b
