Explanation:
Answer:
Explanation:
The mass of the ball is 3 kg.
The velocity of the ball rolling is 3 m/s.
Evaluating and solving for kinetic energy.
The kinetic energy of the ball is 13.5 Joules.
The sound would decrease because the sound waves have nothing to bounce against.
Solution
x(t) = 8 cos t, x(5π/6)= 8 cos(<span>5π/6)
</span>cos(5π/6)=cos(3π/6 + 2π/6 )=cos(π/3 +π/2)= - sin π/3 (cos (x+<span>π/2)= -sinx)
</span>x(t) = -8sin <span>π/3 = - 4 .sqrt3
</span>v(t) = -8sint = -8sin (π/3 +<span>π/2)= -8 cosπ/3 </span>(sin (x+π/2)= cosx)
v(t) =<span> -8 cosπ/3 = -8/2= - 4
</span>a(5π/6) = - 8cost = -(- sin π/3)= 4 .<span>sqrt3
</span>a(5π/6) = 4 .<span>sqrt3</span>
The answer is the last option "Respiration"
