Aforce in the + x-direction with magnitude f(x) = 18.0n -(0.530 n/m)x is applied to a 6.00-kg box that is sitting on the horizontal, frictionless surface of a frozen lake. f(x) is the only horizontal force on the box. if the box is initially at rest at x=0, use the work-energy theorem to determine its speed after it has travelled 14.0 m?

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
