A zookeeper and a monkey. The zookeeper shot a tranquilizer gun with an initial v=30m/s. The monkey was up on a tree 140m high. The zookeeper was a horizontal distance of 40m away from the tree where the monkey was in.. The angle made by the dart's initial V and the ground is 71.57 degrees
Q1 At what height does the bullet hit the monkey?
Q2 How long will it take the dart to hit the monkey, as the monkey falls?
Q3 What is the monkeys speed during free fall?
Q4 What is the maximum height of the zookeepers dart?
Q5 What is v minimum of the dart?
