And the acceleration is zero. Also,
let is applied force,
is the net force,
is the mass and
and
As the acceleration is zero, the net force will also be zero.
.
Now, we know the work done is force times displacement.
So,
So, the total work done by the mover to displace 46 kg crate by 10.4 meters 2.81 kJ.
