Final speed after collision with the wall

v_f = -0.4 m/s

before collision the speed of ball initially

v_i = 0.6 m/s

time taken for the collision

\Delta t = 0.2 s

now as per the formula of acceleration we know that

a = \frac{v_f - v_i}{\Delta t}

now plug in all values in it

a = \frac{-0.4 - 0.6}{0.2}

a = -5.0 m/s^2

so acceleration is - 5 m/s/s for above situation
