Question

What is rhe average velocity od a baseball dropped from rest that falls for 2 seconds?​

Answer 1

19.6m/s

Step-by-step explanation:

Given parameters:

Initial velocity = 0m/s

Time = 2s

Unknown:

Average velocity = ?

Solution:

We can use the final velocity of the ball before landing to determines its average velocity ;

Using;

v = u + gt

v is the final velocity

u is the initial velocity

g is the acceleration due to gravity

t is the time

v = 0 + 9.8 x 2 = 19.6m/s
