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 = ma
The Attempt at a Solution
Fspring = kx
F = 900N/m(0.6m)
F = 540N
That's about as far as I got before not knowing what to do next.
