Work = force × displacement
= 250N × 50m
= 12500 J
the work done is negative because the force of friction and the displacement are acting in the opposite direction.
= 250N × 50m
= 12500 J
the work done is negative because the force of friction and the displacement are acting in the opposite direction.

given that , Force = 250 N ( F )
distance = 50 m ( s )
for calculating work done = F * S
work done - Force * distance
= 250N * 50
= 12500 joules ( 12.5 KJ )
distance = 50 m ( s )
for calculating work done = F * S
work done - Force * distance
= 250N * 50
= 12500 joules ( 12.5 KJ )
And which type of work is it?
positive work done
no, the work done is negative
why
see my answer..i have edited it :)
ys u r rit bcs against the force of friction equal to 250N.
