Asprinter starts from rest and accelerates at 1.5 m/s2 fro 20 meters. what is his final velocity? show work

We can determine the final velocity via the following kinematic equation:

Since the sprinter starts at rest this means the initial velocity is zero, a = 1.5 m/s^2 and the difference of x is 20 meters therefore:

The final velocity is 7.75 m/s

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
