A grandfather clock is constructed so that it has a simple pendulum that swings from one side to the other, a distance of 27.0 mm, in 1.00 s. What is the maximum speed of the pendulum bob?

0.027m/s

Explanation:

The speed of a body is the distance travelled with respect to time taken.

Mathematically;

Speed = Distance/time

Distance = 27.0mm

Time = 1.00secs

Since 1000mm = 1m

27mm = (27/1000) m

27mm = 0.027m

Speed = 0.027/1.00

Speed of the pendulum = 0.027m/s
