A 4.26 kg block starts up a 33.0 degree incline at 7.81 m/s. How far will it slide if the coefficient of kinetic friction is 0.23?

Answer 1

ok, fn=mg*sin33.

friction= mu(fn)

distance up incline= h/sin33

initial KE=fricton work + gpe
1/2 m v^2=mu*mg*sin33*h/sin33 + mgh

compute h, then distance up is h/sin33
