Answer:

Work was done to move the block is 400 J .

Step-by-step explanation:

Formula

Workdone = Fd cos \theta

Where

W is work , F is the force , d is the disatnce .

θ = the angle between the force direction and movement direction

As given

A student pushes a 40-N block across the floor for a distance of 10 m.

As the work is done across the floor thus the value of θ is 0° .

Workdone = (40).(10)cos\ 0^{\circ}

cos 0° = 1

Workdone = 400 J

Therefore the work was done to move the block is 400 J .
