1. The problem statement, all variables and given/known data A crate of mass 9.2 kg is pulled up a rough incline with an initial speed of 1.52 m/s. The pulling force is 110 N parallel to the incline, which makes an angle of 20.6° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 4.94 m. (e) What is the speed of the crate after being pulled 4.94 m? 2. Relevant equations F(f)=mu*N E(k)=(mv^2)/2 U=mgh delta E(k)= E(k1) - E(k2) W=F*d d=(a*t^2)/2 3. The attempt at a solution W=(m*v(f)^2)/2 v(f)=sqrt(2W/m) W=110*4.94=543.4J v(f)=sqrt(543.4*2/9.2)=10.87ms^-1 The computer says that this is wrong though?
