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

Pepsi [2]

Answer: Acceleration of the ball in the given system is 5 meter per Second Square

The laws of motion are used to determine various aspects of an object in motion.

Explanation:

Applying the first law of motion to calculate acceleration; if formula used in first law is given as $v=u+at$

Here we have a final velocity as 40 meter per second and initial velocity as 20 meter per second and time span is given as 2 second applying the given values in the given equation and finding the value of a

$30=20+a \times 2 = a=5 m/s^2$
