A tree has two devices attached to its trunk which are triggered
when objects pass in front of them. The devices are vertically
aligned and are placed 1.50 𝑚 apart, with the bottom one being
0.65 𝑚 above the ground. You climb the tree and decide to
experiment to find out how high ℎ0 above the ground you are.
You release your wallet from your level so that
it will pass in front of the motion detection devices. Once you've
climbed down, you read that the lower device was triggered
0.194 𝑠 after the first one. Neglecting air friction and
assuming that the wallet did not hit any branches on its way down,
how high ℎ0had you climbed the tree?
