The height of a tower is measured by attaching a simple pendulum to its ceiling, whose length is barely enough to stay off the floor. The pendulum is let go from a small angle, and takes 13 s to return to the same location it started from.

a.) How tall is the tower?
? m

If the pendulum mass is let go 0.1 m above the floor,

b.)how fast is the mass travelling as it grazes the floor?
? m/s
