Answer:
4000 J
Explanation:
WORK=FORCE× DISPLACEMENT
WE NEED TO BOTH FORCE AND DISPLACEMENT
FORCE=Ma
BY USING v=u+at
40=0+a×5
a=40/5
a=8 m/s²
FORCE = Ma
=5×8
=40 N
DISPLACEMENT=?
BY USING v²-u²=2as
40²-0²=2×8×s
1600=16×s
s=1600/16
s=100 m
WORK=F×s
=40×100
=4000 J
THE UNIT OF WORK IS NOT NEWTON(N) IT IS JOULES (J).
4000N
