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 #?

Answer 1

Charles Aeschliman

Work #W=831.5575747" "#joules

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 operational formula

#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

May God bless you all. I hope this explanation helps.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
