I hope this helps you, have a great day!

Answer:

The acceleration of a ball is 5 m/s².

Explanation:

Given that,

Initial velocity = 20 m/s

Time = 2.0 sec

Final velocity = 30 m/s

We need to calculate the acceleration

Using equation of motion

[tex]v =u+at[/tex]

[tex]a =\dfrac{v-u}{t}[/tex]

Where, v = final velocity

u = initial velocity

t = time

Put the value into the formula

[tex]a =\dfrac{30-20}{2.0}[/tex]

[tex]a=5\ m/s^2[/tex]

Hence, The acceleration of a ball is 5 m/s².
