<em>Answer:</em>
<em>Uniform motion : </em><em>When a body covers equal distance in equal interval of time irrespective of the direction throughout it's motion</em>
<em>non-uniform motion :</em><em> When it covers a unequal distance in equal interval of time irrespective of the direction throughout it's motion.</em>
<em />
<em>Example of Uniform motion :</em>
<em>The movement of the hands of the clock.
(They move equal distances in equal interval of time.)</em>
<em></em>
<em>Example of non- uniform motion :</em>
<em>An athlete running in a race.</em>

gravity can be considered as *constant* acceleration, then you have:
h = v0*t + 1/2*g*t^2,
Final height is the same as the initial = 0
0 = 11*7 +1/2*g*7^2 ---> g = -11*7*2/7^2 = -22/7 m/s^2
Minus because it goes down, You can say g_planet = 22/7 m/s^2 ~ 3.14 m/s^2. Earth's one on its surface is about 9.81 m/s^2, so this planet has 3 times less gravity. It may be 1/3 the radius of the Earth, assuming same density. This is not asked! :)
Decomposition reactions are said to be those reactions in which a reactants breakdown into two or more products. The general reaction for decomposition reactions is as follow,
ABC → A + B + C
Specific Examples are as,
Water → Hydrogen + Oxygen
2 H₂O → 2 H₂ + O₂
Calcium carbonate → Calcium oxide + Carbon dioxide
CaCO₃ → CaO + CO₂
While, Synthetic reactions are said to be those reactions in which two or more reactants combine to form two or more products. The general reaction for synthetic reactions is as follow,
A + B + C → ABC
Specific Examples are as,
Iron + Oxygen → Iron Oxide
2 Fe + 3 O₂ → 2 Fe₂O₃
Sodium + Chlorine → Sodium chloride
2 Na + Cl₂ → 2 NaCl
Sulfur + Oxygen → Sulfur dioxide
S + O₂ → SO₂
Potassium + Chlorine → Potassium chloride
2 K + Cl₂ → 2 KCl
Answer:
Energy dissipated = 13.453 Joules
Explanation:
In order to solve this problem, we first compute the gravitational potential energy the child has, and then find the kinetic energy at the lowest position.
The gravitational potential energy (relative to lowest position) is found as follows:
G.P.E = mass * gravity * height
Where, Height = 2 - 2 * Cos(34°)
Height = 0.3193 meters
G.P.E = 30 * 9.8 * 0.3193
G.P.E = 93.874 J
Kinetic energy:
K.E = 0.5 * mass * velocity^2
K.E = 0.5 * 30 * 2.31547^2
K.E = 80.421 J
Energy dissipated = G.P.E - K.E
Energy dissipated = 93.874 - 80.421
<u>Energy dissipated = 13.453 J</u>
