Answer:
20 m/s
Explanation:
The acceleration of an object determines the increase in velocity per second.
In this case the acceleration is 20m/s^2.

That is, the increase is 20m/s each second.

The neutron is uncharged. That's why it was
given a name built on "neu" from "neutral".
The period of a simple pendulum is given by:

where L is the length of the pendulum and g is the gravitational acceleration.
The pendulum in our problem makes one complete vibration in 0.333 s, so its period is T=0.333 s. Using this information, we can re-arrange the previous formula to find the length of the pendulum, L:
