Answer:

Pendulum will swing by an angle 0.666π

Step-by-step explanation:

We have given arc = [tex]100\pi cm[/tex]

And length of the pendulum l = 150 cm

Length of the pendulum will be equal to radius of the pendulum so r = 150 cm

Arc is given by [tex]arc=radius\times angle[/tex]

So [tex]100\pi =150\times\times  \Theta[/tex]

[tex]\Theta =0.666\pi[/tex]

So pendulum will swing by an angle 0.666π
