Question

Calculate the work done in pushing a cart through a distance of 50 m against the force of friction equal to 250 N. Also state the type of work done.
​

Answer 1

Answer:

12500joule

Explanation:

w=F.S

50×250=12500joule

It is negative work done

Answer 2

Answer:

We are given that

Force (F)=250N, displacement (s)=50w

∴ Work done=F×S

=250×50

=1250Joule

Here, the work done is negative
