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

$v =u+at$

$a =\dfrac{v-u}{t}$

Where, v = final velocity

u = initial velocity

t = time

Put the value into the formula

$a =\dfrac{30-20}{2.0}$

$a=5\ m/s^2$

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