Answer:
a = - 5 m/s²
Explanation:
The acceleration of the ball can be found by using the general formula of acceleration as follows:
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:
Therefore, the correct option is:
<u>a = - 5 m/s²</u>

Dermatitis is a general term that describes an inflammation of the skin. Dermatitis can have many causes and occurs in many forms. It usually involves an itchy rash on swollen, reddened skin.
Skin affected by dermatitis may blister, ooze, develop a crust or flake off. Examples of dermatitis include atopic dermatitis (eczema), dandruff and rashes caused by contact with any of a number of substances, such as poison ivy, soaps and jewelry with nickel in it.
