1. The problem statement, all variables and given/known data A grasshopper leaps into the air from the edge of a vertical cliff, as shown in the figure below. 2. Relevant equations Use information from the figure to find the height of the cliff. 3. The attempt at a solution The first question was to find the initial speed of the grasshopper. I found this to be 1.5m/s. I have tried using this equation to get the height of the cliff but it isn't right: h = ut + (1/2)gt2 where u is the initial velocity. Any help is greatly appreciated.
