Calculate the period of oscillation of a pendulum with a small amplitude whose length is 2.5 meters

T = 3.17 s

Explanation:

Given that,

The length of the pendulum, l = 2.5 m

We know that the period of oscillation of the pendulum is given by :

Where

g is the acceleration due to gravity

So, the period of oscillation is equal to 3.17 s.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
