How to start a rigid body simulation on a frame that is later than frame one

I want to animate A truck crashing back doors opening and barrels flying out of the back, I want to use the simulation on the barrels but I don’t want the simulation to start until frame 143 but have no idea how

the barrels are both parented to the truck and also have their own keyframes for when they fly out of the truck (I don’t know if that will make a difference in the final result) I also attached the .blend just in case

truck crash drums crash.blend (1.75 MB)

In the Rigid Body tab, check Animated. Key frame it unchecked when you want the simulation to take over.
