Two beetles are walking in the same direction on the straight edge of a large greenhouse roof. Beetle 1 (leader) pauses, while Beetle 2 (follower) keeps moving at 0.075 m/s: Beetle 2 needs to slow down to avoid bumping into Beetle 1โ€™s rear end. Beetle 2 starts slowing down (att= 0)when it is 0.255 m behind Beetle 1. Beetle 2 will eventually stop, without bumping into its friend. (a)What is the least average acceleration that Beetle 2 would have to apply to stop just behindBeetle 1, without accidentally climbing on it? (b)Actually, the prudent Beetle 2 applies twice that minimum acceleration: how far does it actually stop from Beetle 1?
