Question

How far will a baseball travel if it's speed is 10 m/s and it comes to a stop after 3s

Answer 1

We know, v = d / t
Here, v = 10 m/s
t = 3 s

Substitute their values, 
10 = d / 3
d = 10 * 3
d = 30 meters

In short, Your Answer would be 30 m

Hope this helps!

Answer 2

You use the equation d=velocity*time, so d=(10 m/s)(3s). Therefore, distance is 30 meters
