The average acceleration is -5.0 m·s⁻².
The formula for acceleration (<em>a</em>) is
= 25 m·s⁻¹; 
= 0; 
= 5.0 s
∴ 
= -5.0 m·s⁻²
The negative sign tells you that the object is <em>slowing down</em>, i.e., it is <em>decelerating</em>.
Answer:
25 mph
Explanation:
So we have to find the unit rate, or you could use the DTS triangle, but both say you have to divide, so our equation is:
176 ÷ 7 = 25.14
But I'm going to round that
So the train is traveling at 25 mph

The glow stick's outer plastic tube holds a solution of an oxalate ester and an electron-rich dye along with a glass vial filled with a hydrogen peroxide solution. ... Glow sticks light up when oxalate esters react with hydrogen peroxide to form a high-energy intermediate
Answer: The frequency of this light is 
Explanation:
To calculate the wavelength of light, we use the equation:
where,
= wavelength of the light =
c = speed of light = 
= frequency of light = ?
The frequency of this light is
