At t = 0, a cart of mass m = 5 kg starts rolling down an incline, making an angle α = 20o with the horizontal. Initially the cart rolls down with no friction, but after traveling a distance of ∆ = 10 m it encounters a rough surface, where the coefficient of friction is k = 0.45. Find the acceleration of the cart along the incline (positive direction is downhill) after it encounters the rough surface. A.9.8 m/s2 B.9.2 m/s2 C.7.7 m/s2 D.3.6 m/s2 E.3.4 m/s2 F.-0.8 m/s2
