Use the illustration below to determine the average speed and displacement, if you walk 4 meters East, 2 meters South, 4 meters
West, and finally 2 meters North. The entire motion lasted for 24
seconds.

Explanation:

the average speed = (4+2+4+2)m /24 s

= 20/24

= 0.83 m/s

the displacement = 0 (back to the origin position)

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
