$141 : 30414 91 : 7. Two identical sleds A, and B start moving at the same time d - 15 n from the same point A. One goes on a bridge with initial speed vo, the other goes down into the ditch with the same initial speed vo at point /A. Assume that Vo is 10.0 m/s, the angle of the slope is 0 = 45,0 and d'is 15.0 m. Neglect any friction in this problem. (1) What is the speed of the second sled at the bottom of the ditch (at point B)? (2) Find the time that the second sled needs to reach the bottom of the ditch (A -B). (3) Is the time that the first sled takes to move from point A to point C on the bridge larger, equal or less than the time the second sled takes to go to the bottom of the ditch (A -B)? we can Know that =AB (4) Find the net force acted on each sled (A, and B)?
