You pull your little sister across a flat snowy field on a sled. your sister plus the sled have a mass of 20 kg. the rope is at an angle of 35 degrees to the ground . you pull a distance of 50 m with a force of 30 n how much work do you do?

1228.72 N

Explanation:

Given

Combined mass(m)= 20 kg

rope is at an angle of

Distance pulled =50 N

Force= 30 N

there will be two components of force

and

will do work while the work will be as angle between force and displacement is zero

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
