Answer:
( 688.29 , 276.66 ) meters
Explanation:
Break into horizontal and vertical components
x = 100 cos 55 = 57.36 m/s
the x coordinate is then 12 seconds * 57.36 m/s =<u> 688.29 meters </u>
y coordinate is a bit more complex because of the curved path due to gravity
Original y velocity = 100 sin 55
y = vo t - 1/2 (9.81)(t^2)
y = 100 sin 55 (12) - 1/2 (9.81) (12)^2
yf = <u>276.66 meters </u>

Answer:
Reactants: Fe, and
Product:
Explanation:
Two electrochemical reactions occur during the formation of rust;
- Oxidation of iron (Fe) in water:
- Reduction of oxygen in water:
The two products from the two electrochemical equations then react together to form iron hydroxide.
The iron hydroxide thus produced slowly reacts with oxygen to form rust which is .
<em>Hence, the reactants are iron (Fe), water (</em><em>) and oxygen (</em><em>) while the product is rust (</em><em>).</em>
Potential: very top of the roller coaster, awaiting the drop. Kinetic: on its way down the largest drop
