Julie, mass 36kg, has invented a new ride called the Human Launcher. It is basically a platform that springs people straight up into the air. She is testing it, standing on a bathroom scale on the platform. As the platform springs 10.0m upward from rest, Julie notices the scale reads 600.0N. Once it reaches ground level, the platform suddenly stops, but Julie doesn't, and is launched up into the air. What is the maximum height above the ground that Julie will reach? (the ride was deemed unsafe and cancelled) *= nut 10.0m ground

A very bored 318 kg bear decides to jump across a stream. The stream is 6 m wide and the east bank of the stream is 1m higher than the west bank (where the bear starts). The bear can jump with an initial velocity vi (4m/s, 4m/s) , and decides to start from 3m in the air, halfway up a sturdy tree. Part 1 If the origin is at the bear's foot (up in the tree), write an equation describing the coordinate of the bear while it is in the air. Use the following table as a reference. Note that it may not be necessary to use every variable. For Use Δt t g g
