How much work would it take to push a # 3 kg # weight up a # 7 m # plane that is at an incline of # pi / 6 #?

1 Answer

Answer:

Work #W=102.9" "#Joules

Explanation:

The force #F# required to push a weight a distance #d=7" "#meters up parallel to the incline plane at #theta=pi/6=30^@# is

#F=mg*sin theta#

considering no frictional force is involve

The work #W#:

#W=F*d=mg*sin theta*d=3(9.8)*sin (pi/6)*7#

#W=102.9" "#joules

God bless....I hope the explanation is useful.
