            H = Maximum Height of Projectile =   
             
 R = Horizontal Range of Projectile =   
             
 t = Time to rise up 
              to P =   
              The monkey jumping off at t = 0 will descend down 
              by distance , 
                
              \ After t = t 
              the monkey is at the height of   
              from the ground.
