A pack with a mass of 25 kg with wooden roofing in a
man has a slope of 35
pushing it to the roof. Between previously installed wooden roof
coverings and the package
The kinetic friction coefficient is 0.32. 0.2 m / s of the package
^ 2
up the roof with the acceleration
Find the force required to push it. (Take g = 9.8 m / s ^ 2.)
Solution
It is not clear from Question whether 0.2m/s^2 is the upward acceleration of package or is it just a typo. However I have done both calculations for you (with and without acceleration) see the attached,
