Question

                    Bear is rather small, with a mass of only about 50.3kg, including his equipment. The crossing distance is roughly W=14.5 m and the rope is tied H=2.90 m lower                    on the opposing the bank. Judging by the sag in the rope, its length is about 18.5 m.                 

                    1- Calculate the tension in the rope once Bear reaches a point of equilibirium. Assume the rope does not stretch.                 

                    2- If Bear can make it far enough across (at least 11 m from where he starts), he can drop down onto the river bank below. How far will he travel across?                 

                    3- A crewman expert on ropes claims that the condition of the rope would not allow it to hold a tension more than 596 N before snapping. Based on this                    information and your calculations, what do you tell Bear?                 

                    A- don't do it , the rope will snap                 

                    B- don't do it the rope will probably hold, but you'll never make it across the river.                 

                    C- No problem The rope is strong and you will get far enoughacross.
