Homework Statement A crate of mass 10.2 kg is pulled up a rough incline with an initial speed of 1.42 m/s. The pulling force is 94.0 N parallel to the incline, which makes an angle of 20.7° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 4.92 m...

oh yeah.. so should it be (-1/2)Ax^2 + (1/4)Bx^5 ? i'm not sure what form my final answer should be.

Homework Statement A single conservative force acting on a particle varies as Fvec = (-Ax + Bx4)i N, where A and B are constants and x is in meters. Accurately round coefficients to three significant figures. (a) Calculate the potential energy function U(x) associated with this force, taking U...

Homework Statement Find f(n) when n = 2^k, where f satisfies the recurrence realtion f(n) = f(n/2) +1 with f(1) = 1 Homework Equations f(n) = a*f(n/b) + c when n = b^k, where k is a positive integer, f(n) = C1n^(log a base b) + C2 C1 = f(1) +c/( a-1) and C2 = -c/ (a-1) keep in mind...
