A kilogram weighs about 2.2 pounds.
(a) Write a formula for the function, f, which gives an object's mass in kilograms, k, as a function of its weight in pounds, p.
(b) Find a formula for the inverse function of f. What does this inverse function tell you, in practical terms?
In the 1950s, an experimental train that had a mass of 2.00 104 kg was powered across a level track by a jet engine that produced a thrust of 5.30 105 N for a distance of 509 m. Assume that air resistance is negligible.
A m = 2.0-kg block sits on a M = 4.0-kg block. There is no friction between m and M. There is no friction between M and the surface below it. If F = 12 N, which blocks move and what is their acceleration?
A cart is attached to a hanging mass by a string that passes over a pulley. Write an equation for the work done by friction when the cart is moving up the track at constant speed
