this question has 4 parts, im having trouble on the last part but i will post all parts to give context. Part A How much work is done by the horizontal force FP = 150 N on the 18-kg block of the figure(Figure 1) when the force pushes the block 5.5m up along the 32∘ incline? Assuming a coefficient of friction μk = 0.14. [Hint: Work-energy involves net work done.] for WFp i got 700 J Part B How much work is done by the gravitational force on the block during this displacement? for Wgr i got -510J Part C How much work is done by the normal force? for WN i got 0 J Now the part that im having trouble Part D What is the speed of the block (assume that it is zero initially) after this displacement? To do this part I did initially I used the equation Wnet = 0.5mv2, with Wnet = WFp + Wgr + WN so Wnet = 190 and i solved for v by v = sqrt(2W/m) and got 4.6 m/s that answer is incorrect. After consulting with my professor she said to take friction into account but now im not sure how to do so. I know that the normal force is mgcosθ + Fpsinθ and then the work of friction is equal to μk*FN*d*cosθ I tried that and ended up with the velocity = 6.1 m/s is there something im not seeing?
