25. 0 kg dog is trapped on a rock in the middle of a narrow river. A 66. 0-kg rescuer has assembled a swing with negligible mass that she will use to swing down and catch the trapped dog at the bottom of her swing, and then continue swinging to the other side of the river. The ledge that the rescuer swings from is 5. 0 m above the rock, which is not high enough so the rescuer and dog together can reach the other side of the river, which is 3. 0 m above the rock. However, the rescuer can use a ladder to increase the height from which she swings. What is the minimum height of the ladder the rescuer must use so both dog and rescuer make it to the other side of the river? Assume that friction and air resistance are negligible
