How much work would it take to push a # 8 kg # weight up a # 15 m # plane that is at an incline of # pi / 4 #?

1 Answer

Answer:

Work #W=831.5575747" "#joules

Explanation:

The given data are
mass #m=8" "#kg
angle #theta=pi/4#

distance #d=15" "#meters

Let #F# be the force required to push the object up the plane

the working equation

#F=mg*sin theta#
#F=8*(9.8)*sin (pi/4)#
#F=55.43717165" "#N

Solve for the work #W#

#W=F*d#
#W=55.43717165(15)#
#W=831.5575747" "#Joules

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