Answer:

5m/s^2

Explanation:

we know that,

a=dv/dt.

a=40-0/8

a=40/8

a=5m/s^2.

(the S.I unit of accereration is m/s^2.)

Answer: acceleration = 5 m/s²

Explanation:

We know that

v = u + a*t

Where u = initial velocity; v = final velocity; a = acceleration and t = time

Using this formula and substituting the values, we get

40 = 0 + a*8

=> a * 8 = 40

=> a = 40/8 = 5 m/s²

Acceleration = 5 m/s²
