I mixed some of the numbers apparently. Fspring = kx F = 900N/m(0.4m) F = 360N 40kg x 9.8 = 392N Ff = μk(FN) Ff = 0.6(392N) Ff = 236N Fnet = Fa - Ff Fnet = 360N - 236N Fnet = 124N Fnet = ma Fnet/m = a 124N / 40kg = a 3.1 m/s2 = a Evidently that was a lot easier than I made it out to be...

What exactly do you mean that they are two different forces? In the section that you quoted, isn't there only one force being calculated: the spring force? And p.s, I made a typing error. Where it says 0.4, it should be 0.6

Homework Statement A duck of mass 40kg is being pulled by a spring with k = 900N/m. If μk = 0.6 between the duck and the road, find the acceleration of the duck given that the spring stretches 0.4m.Homework Equations Fspring = kx, where k = spring constant and x = stretch of spring Fnet = maThe...

Homework Statement Fill in the missing quantity for the following: V = constant FNet = ? a = ? F1 = ?Homework Equations FNet = Fn - Fg + Fa - FF Fg = mg FNet = maThe Attempt at a Solution Because I honestly do not know how to go about solving this, the only things I've done are review class...
