The document contains equations to calculate the maximum height of an object thrown upward with an initial velocity. It uses the equations of motion X=Xo+Voxt+1/2gt^2 and t^2=2x/g to find the time of 2.5 seconds for the object to reach a height of 2.5 meters. It then uses this time in the equation Y=Yo+Voyt-1/2gt^2 to calculate the object's height after 0.71 seconds as being 2.47 meters.
