Answer:

a = - 5 m/s²

Explanation:

The acceleration of the ball can be found by using the general formula of acceleration as follows:

a = \frac{\Delta V}{\Delta t}

where,

a = acceleration of ball = ?

ΔV = change in velocity = Final Velocity - Initial Velocity

ΔV = - 0.4 m/s - 0.6 m/s = -1 m/s

Δt = time of contact with the wall = 0.2 s

Therefore, using the values in equation, we get:

a = \frac{-1\ m/s}{0.2\ s}\\\\a = -5\ m/s^2

Therefore, the correct option is:

<u>a = - 5 m/s²</u>
