a softball player moving 3.89 m/s starts a slide, decelerating at -1.44 m/s^2 for 4.80 m. how much time does the slide take? (she does not come to a stop)

Explanation:

We have,

Initial speed of a softball is 3.89 m/s

Deceleration of the ball is -1.44 m/s²

Distance covered by the ball is 4.8 m

It is required to find the time that the ball take when it slides. Let t is time. Using second equation of motion :

Putting all the values we get :

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
