A 70kh 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 when it is stretched by 1.50 m.
The mass of the sled and its two riders in Figure 5.5 is 214 kg. Find the magnitude of the centripetal force that acts on the sled and its two riders during the turn with a radius of 30.0 m, if the speed is equal 34.0 m/s.
