Problem 8: The length of nylon rope from which a mountain climber is suspended has a force constant of 1.55 × 104 N/m. Part (a) What is the frequency, in Hz, at which he bounces, given his mass and the mass of his equipment is 86 kg? Numeric : A numeric value is expected and not an expression. f = __________________________________________ Part (b) How much would this rope stretch, in centimeters, to break the climber's fall if he free-falls 1.4 m before the rope starts to stretch? Numeric : A numeric value is expected and not an expression. x = __________________________________________ Part (c) What is the frequency, in Hz, at which he bounces, given his mass and the mass of his equipment is 86 kg if the rope is twice as long? Numeric : A numeric value is expected and not an expression. f2 = __________________________________________ Part (d) How much would this rope stretch, in centimeters, to break the climber's fall if he free-falls 1.4 m before the rope runs out of slack if the rope was twice the length? Numeric : A numeric value is expected and not an expression. x2 = __________________________________________
