Answer:
Work was done to move the block is 400 J .
Step-by-step explanation:
Formula
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° .
cos 0° = 1
Workdone = 400 J
Therefore the work was done to move the block is 400 J .
