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.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
