The work done by friction hurts, hence it has negative mu . I just have them switched in the addition problem above. I have no clue what LaTeX is, although I see when I try to copy and paste your mu, LaTeX Code: \\mu, it shows up as an odd code. I'm new to these forums and have not been...

Homework Statement The 10kg block has an initial velocity of 2m/s at the bottom of the ramp and slides up the ramp with a constant applied horizontal force F=75N as shown. Find the maximum height h that the block can reach on the ramp. We're using cos(theta/%)=.8 & sin(theta/%)=.6...

Problem with that is we haven't learned anything about energy yet so we are supposed to use regular Work, Power, and other Motion formulas.

Homework Statement What power is needed to drive a car at 60 km/h up a 10% grade. mass=1800kg v=60km/h theta=5.7106 g= 9.81 m/s^2 Homework Equations P = Fv P_ave= W/T w=mg F=maThe Attempt at a Solution I drew my diagram and FBD. Since Fy=mAy=0.. 0=N-sin(5.7106) N=1755.2477 I know that...
