A70kh man jumping from a window lands in an elevated
firerescue net 11.0 m below the window. he momentarily stops when
hehas stretched the net by 1.50 m. assuming that mechanicalenergy
is conserved during this process and the net functions likean ideal
spring, find the leastic potential energy of the net whenit is
stretched by 1.50 m.
