Find the speed of the pendulum at the bottom of the first swing.
the mass on the pendulum is 200g
the mass is suspended 93 cm from the floor

There's not enough information given to answer the question.

The speed depends on the kinetic energy of the bob at the bottom of
the first swing.

THAT depends on how high above its 'resting' position it was before
it was released, and THAT depends on how long the string is and
how far to the side you pulled it before you let it go.
