Suppose you pull a 45 N wooden box on a rough flat surface by pulling on the box with a horizontal force P, acting to
the right. Assume the frictional force is 3 N.
A) Determine the magnitude of P if the box is pulled at a constant velocity.
B) Assume the box was initially at rest, determine P to displace the box 3 m in 2 seconds.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
