Question

What is the acceleration of a ball traveling horizontally with an initial velocity of 20 meters/second and, 2.0 seconds later, a velocity of 30 meters/second?

Answer 1

The answer would be a=5 m/s^2
I hope this helps you, have a great day!

Answer 2

The acceleration of a ball is 5 m/s².

Step-by-step 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 =(v-u)/(t)`

Where, v = final velocity

u = initial velocity

t = time

Put the value into the formula

`a =(30-20)/(2.0)`

`a=5\ m/s^2`

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