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 0=45 bottom of the ditch (at point B)? 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 + hat = AB (4) Find the net force acted on each sled (A, and B)?
