The displacement in simple harmonic motion is maximum when the velocity is zero
Answer: Option 5
<u>Explanation:
</u>
Displacement is the measure of variation between the end position and starting position. So displacement is path independent, it is completely based on them. As in simple harmonic motions, the net displacement is zero if the velocity seems to be maximum.
Because the motion of simple harmonic is to return to the starting point for a single oscillation. So, the displacement is opposite directions to the velocity. Thus if the displacement is required to be maximum for the simple harmonic motions, the velocity should be zero.
Initial speed(u)=0m/s
Final speed(v)= 27m/s
Time(t)=7.6s
Use the equation of motion: v = u + at
27 = 0 + a(7.6)
27/7.6 = a
a = 3.55 m/s^2 (3 s.f)
Answer:
velocity and acceleration are zero.
Answer: D. Energy is always conserved
Explanation: The law of energy conservation says that energy is neither created or destroyed, that it is only transferred or transformed from energy. "Conserved" means to maintain a constant overall total, which ties directly into the law of conservation (Energy can't be created nor destroyed, it can only be transferred or transformed from one form to another).
