applied force is parallel. and no its not from txtbook

*correction- kinetic friction*. frictional force,the gravitational force,applied force and normal force.The work done by gravitational force=-245.25J,energy lost by overcoming friction=-169.92J,work done by force,120N=600J, and the total work done i found was 184.83J. so how do I get the...

the velocity of the block after it has move 5m up the plane

10kg block is pulled up an incline plane at 30 degree with horizontal in distance 5.0m by force 120N.coefficient of kinetic energy 0.4. help!how do you get the velocity of block? answer: v=3.48ms^-1

k thanks for your help.

it helps abit but i got (-745.17J) tho

well,the answer for work done to overcome friction is WFf= -745.36J. wonder why was that.

done that and got kE=360.15J

im having a hard time to solve this work done by overcoming friction question. help please? Question: a block with mass 30kg slide on a rough inclined plane with 8m long and 28 degree to horizontal with acceleration 1.5ms^-2. a)Calculate the work done to overcome friction. b)the coefficient of...
