An object of mass m slides down a slope of Ɵ angle with µ(kinetic) friction. velocity is V(zero) at t=0.
Under what conditions does the object stop sliding? Show how you found this requirement.hint: a=F(net)/m, find an inequality
Show that the acceleration of any object down an incline where friction behaves simply (that is, where fk=μkN)fk=μkN) is a=g(sinθ−μkcosθ).a=g(sinθ−μkcosθ). Note that the acceleration is independent of mass and reduces to the expression found in the previous problem when friction becomes negligibly small (μk=0).(μk=0).
A cake rests in a cardboard box on the horizontal surface of the seat of your car which is traveling at 11 m/s. If the coefficients of friction are µk = 0.3 and µs = 0.5, find the minimum stopping distance necessary to keep the cake box from sliding off the seat.

However, this speed is inadequate to compensate for the kinetic friction between the puck and the ice.
