Amass of 100 kg is pulled by a 392 n force in the +x direction along a rough surface (uk=0.4) with uniform velocity v=20 m/s. what is the total work done by all forces on the object after s=10 m?

The total work done will be zero.

Explanation:

Given that,

Mass = 100 kg

Force = 392 N

Velocity = 20 m/s

Distance s= 10 m

We need to calculate the work done

Using balance equation

The net force will be

The net force is zero.

Hence, The total work done will be zero by all forces on the object.

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
