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?

The acceleration of the ball is 5 m/s^2. This can be calculated using a formula that relates the change in velocity, acceleration, and time. This formula is:

Vf = Vi + at

where:

Vf = final velocity

Vi = initial velocity

a = acceleration

t = time

Substituting the values gives:

30 = 20 + a (2)

a = 5 m/s^2 - - > Final Answer
