When a pendulum is pulled back from its equilibrium position by 10∘, the restoring force is 1.0 N. When it is pulled back to 30∘, the force increases to 2.8 N. If the pendulum is then released from 30∘, will its motion be periodic? If the pendulum is then released from 30, will its motion be periodic?a) No, it will be linear motion.b) No, the motion will be chaotic.c)Yes and it will be exactly harmonic.d)Yes, but it will not be exactly harmonic.

Respuesta :

Answer: B

Explanation: I said B because if you pull something back what is going to be more of a force pulling back or letting it go for a rubier band yes it will have more force if you let it go

Answer:

The answer is d) Yes, but it will not be exactly harmonic: the pendulum’s motion will be periodic, but will not be exactly harmonic because the condition for simple harmonic motion is not satisfied when angular displacements become larger. Typically, a pendulum’s motion will exhibit simple harmonic motion if angular displacements are smaller.
