A student tries to raise a chain consisting of three identical links. Each link has a mass of m. The three-piece chain is connected to a string and then suspended vertically, with the student holding the upper end of the string and pulling upward. Because of the student's pull, an upward force of F is applied to thechain by the

1. Express the distance between the point (3, 0) and the point P (x, y) of the parabola y = as a function of x.
2. Find a function f(x) = and a function g such that f(g(x)) = h(x) =
3. Find the trigonometric limit: .
4. Given , use the four step process to find a slope-predictor
function m(x). Then write an eq

Question 5
A bucket that weighs 6 lb and a rope of negligible weight are used to draw water from a well that is 90 ft deep. The bucket is filled with 42 lb of water and is pulled up at a rate of 2.5 ft/s, but water leaks out of a hole in the bucket at a rate of 0.25 lb/s. Find theworkdone in pullingthe bucket to thetop of t

To pull a car from a ditch, the driver ties one end of a rope to the car and the other to a tree 12.5 m away. Driver then pulls sideways from the midpoint of the rope with a 475 N force.
How much force exterted on the car whenthe rope has been pulled 75 cm to one side?

1) The motor of a ski boat generates an average power of 35900 W whenthe boat is moving at a constant speed of 17.7 m/s. Whenthe boat is pulling a skier at the same speed, the engine must generate an average power of 80700 W. What is the tension in the tow rope that is pullingthe skier?
2) The drawing shows the force-versu

Explain why thework required to pull a dynamics cart up an incline, in the absence of friction, should be the same as thework required to lift the cart vertically through the vertical displacement it experiences in the process.

A student could either pull or push, at an angle of 300 from the horizontal, a 50-kg crate on a horizontal surface, where the coefficient of kinetic friction between the crate and surface is 0.20. The crate is to be moved a horizontal distance of 15 m.
(a) Compared with pushing, pulling requires the student to do
(1) less,
