Explanation:
Some of the ball’s energy is transformed to thermal energy.
The rolling ball loses some of its energy because of gravity.
The ball absorbs some of its own potential energy.
Some of the ball’s energy is transformed to thermal energy.
The principle of conservation of energy states that sum of potential energy and kinetic energy is constant.
M.A = P.E + K.E
where;
The mechanical energy is always conserved, although it may be converted from one form to another.
The rolling ball follows the law of conservation of energy, the lost energy may be transformed to thermal energy.

Answer:
84.9°
Explanation:
You correctly found the acceleration and the net force in the x direction. Now write the net force as the sum of the x components of the individual forces.
∑F = F₁ + F₂ cos θ
3.6 = 2.8 + 9.0 cos θ
0.8 = 9.0 cos θ
0.0889 = cos θ
θ = ±84.9°
F₂ is either 84.9° above the x-axis or below the x-axis.

Answer:
Density → Mass and Length.
Acceleration → Length and Time.
Force → Mass, Length and Time.
Pressure → Mass, Length and Time.
Work → Mass, Length and Time.
