I removed the rigid body you added and added it again to all your 3 objects because I wanted to change the settings. Copy the settings with the help of the GIF given below
Change the end time in the cache settings to change the rigid body animation length because by default the rigid body animation always ends at frame 250 even if you change the animation length in the timeline. For example, if you set the value of the end frame under the cache settings to 'x' that means the rigid body animation will go up to frame number 'x'
A small clip of the result.
If you find your animation too slow or fast you can always change the speed in the scene properties like this.
Hope this helps and works for you :)
