Simple Harmonic Motion. Mass & Energy II

Characateristics of the Simple Harmonic Motion are:

Three options

• The movement is not periodic

• The movement is periodic

• There's no friction force

• It's produced by a restitution force

The wheel of a bike turns at 160 rpm..., what's the angular velocity value?

The wheel of a bike turns at 160 rpm and it considers a radius of 0.4 m. How could you calculate its linear velocity?

The wheel of a bike turns at 160 rpm and it considers a radius of 0.4 m. What's its linear velocity?

Why the force considered by Hooke's law is negative?

• Because teacher said...

• Because it's an applied force.

• Because it's a force of restitution.

• Becuase Hooke forgot to erase the negative symbol.

• True

• False

What's the spring constan that a suspension system presents when it's compressed 0.019m, supporting a mass of 50kg on top of it.
