## Homework Statement

1) Find the period of a pendulum 50 cm long when it is suspended in (a) a stationary elevator; (b) an elevator falling at the constant speed of 5.0 m/s; (c) an elevator falling at the constant acceleration of 2.0 m/s2; (d) an elevator rising at the constant speed of 5.0 m/s; (e) an elevator rising at the constant acceleration of 2.0 m/s2.

## Homework Equations

Period = 2 pi Squareroot of Length of arm/ Gravity

## The Attempt at a Solution

1) I could solve a) by simply replacing data into the formula, but im not sure how does the change in velocity and acceleration affects the data that is where im stuck at.
