The length of nylon rope from which a mountain climber is suspended has an effective force constant of 1.40×104n/m .
(a) what is the frequency at which he bounces, given his mass plus and the mass of his equipment are 90.0 kg?
(b) how much would this rope stretch to break the climber’s fall if he free-falls 2.00 m before the rope runs out of slack? (hint: use conservation of energy.)
(c) repeat both parts of this problem in the situation where twice this length of nylon rope is used.

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
